Jun 3, 2026MasterStudy LMS Pro Plus: Generic SQL InjectionCVE-2026-8653 · WordPress plugins & themes · reported by WordfenceMedium 6.5
The MasterStudy LMS Pro Plus plugin for WordPress is vulnerable to generic SQL Injection via the 'columns' parameter in all versions up to, and including, 4.8.20 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with instructor-level access or above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Lightweight Music Server (LMS) though 3.76.0 contains a stored cross-site scripting vulnerability that allows attackers to execute arbitrary JavaScript by embedding malicious HTML in media file metadata tags such as GENRE, ARTIST, or ALBUM. Attackers can introduce a crafted media file into the victim's library, causing the payload to be saved during library scanning and executed automatically in the web interface due to tag content being rendered using Wt::TextFormat::UnsafeXHTML without sanitization in src/lms/ui/Utils.cpp.

May 27, 2026In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Add missing save/restore handling of LBR MSRs MSR_IA32_DEBUGCTLMSR and LBR MSRs CVE-2026-46014 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67Medium 5.5
In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Add missing save/restore handling of LBR MSRs MSR_IA32_DEBUGCTLMSR and LBR MSRs are currently not enumerated by KVM_GET_MSR_INDEX_LIST, and LBR MSRs cannot be set with KVM_SET_MSRS. So save/restore is completely broken. Fix it by adding the MSRs to msrs_to_save_base, and allowing writes to LBR MSRs from userspace only (as they are read-only MSRs) if LBR virtualization is enabled. Additionally, to correctly restore L1's LBRs while L2 is running, make sure the LBRs are copied from the captured VMCB01 save area in svm_copy_vmrun_state(). Note, for VMX, this also fixes a flaw where MSR_IA32_DEBUGCTLMSR isn't reported as an MSR to save/restore. Note #2, over-reporting MSR_IA32_LASTxxx on Intel is ok, as KVM already handles unsupported reads and writes thanks to commit b5e2fec0ebc3 ("KVM: Ignore DEBUGCTL MSRs with no effect") (kvm_do_msr_access() will morph the unsupported userspace write into a nop).

The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to payment bypass through user-controlled key in all versions up to, and including, 4.3.5. This is due to improper handling of user-supplied request parameters in the REST API endpoint, which passes the unsanitized parameter array to the add_to_cart() function where array_merge() allows attacker-controlled values to overwrite hardcoded defaults. This makes it possible for authenticated attackers, with subscriber-level access and above, to enroll in any paid course entirely free of charge by supplying a quantity value of zero, which causes the order total to calculate as $0 and bypasses all payment gateway requirements.

May 13, 2026Tutor LMS – eLearning and online course solution: Insecure Direct Object ReferenceCVE-2026-6965 · WordPress plugins & themes · reported by WordfenceMedium 5.3
The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 3.9.9. This is due to the `get_course_id_by()` function unconditionally trusting the user-supplied `course` GET parameter as the authoritative course ID for content ownership lookups, which is then consumed by `can_user_manage()`, the plugin's sole authorization gate for instructor-level operations, causing it to evaluate instructor membership against the attacker-controlled course rather than the course that actually owns the target content object. This makes it possible for authenticated attackers, with instructor-level access and above, to perform unauthorized operations on any other instructor's course content, including permanently deleting lessons, assignments, quizzes (with cascading deletion of all student attempt data), topics, announcements, and Q&A threads, as well as creating or modifying lessons, topics, and announcements in victim courses, manipulating student quiz grades, and reading unpublished lesson and quiz content.

vLLM is an inference and serving engine for large language models (LLMs). From 0.18.0 to before 0.20.0, the extract_hidden_states speculative decoding proposer in vLLM returns a tensor with an incorrect shape after the first decode step, causing a RuntimeError that crashes the EngineCore process. The crash is triggered when any request in the batch uses sampling penalty parameters (repetition_penalty, frequency_penalty, or presence_penalty). A single request with a penalty parameter (e.g., "repetition_penalty": 1.1) is sufficient to crash the server. This vulnerability is fixed in 0.20.0.

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlink_log: initialize nfgenmsg in NLMSG_DONE terminator When batching multiple NFLOG messages (inst->qlen > 1), __nfulnl_send() appends an NLMSG_DONE terminator with sizeof(struct nfgenmsg) payload via nlmsg_put(), but never initializes the nfgenmsg bytes. The nlmsg_put() helper only zeroes alignment padding after the payload, not the payload itself, so four bytes of stale kernel heap data are leaked to userspace in the NLMSG_DONE message body. Use nfnl_msg_put() to build the NLMSG_DONE terminator, which initializes the nfgenmsg payload via nfnl_fill_hdr(), consistent with how __build_packet_message() already constructs NFULNL_MSG_PACKET headers.

Apr 17, 2026Tutor LMS – eLearning and online course solution: Unauthorized course content manipulationCVE-2026-5502 · WordPress plugins & themes · reported by WordfenceMedium 5.3
The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized course content manipulation in versions up to and including 3.9.8. This is due to a missing authorization check in the tutor_update_course_content_order() function. The function only validates the nonce (CSRF protection) but does not verify whether the user has permission to manage course content. The can_user_manage() authorization check only executes when the 'content_parent' parameter is present in the request. When this parameter is omitted, the function proceeds directly to save_course_content_order() which manipulates the wp_posts table without any authorization validation. This makes it possible for authenticated attackers with subscriber-level access and above to detach all lessons from any topic, move lessons between topics, and modify the menu_order of course content, effectively allowing them to disrupt the structure of any course on the site.

Apr 16, 2026MasterStudy LMS WordPress Plugin for Online Courses and Education: Time-based Blind SQL InjectionCVE-2026-4817 · WordPress plugins & themes · reported by WordfenceMedium 6.5
The MasterStudy LMS WordPress Plugin for Online Courses and Education plugin for WordPress is vulnerable to Time-based Blind SQL Injection via the 'order' and 'orderby' parameters in the /lms/stm-lms/order/items REST API endpoint in versions up to and including 3.7.25. This is due to insufficient input sanitization combined with a design flaw in the custom Query builder class that allows unquoted SQL injection in ORDER BY clauses. When the Query builder detects parentheses in the sort_by parameter, it treats the value as a SQL function and directly concatenates it into the ORDER BY clause without any quoting. While esc_sql() is applied to escape quotes and backslashes, this cannot prevent ORDER BY injection when the values themselves are not wrapped in quotes in the resulting SQL statement. This makes it possible for authenticated attackers, with subscriber-level access and above, to append arbitrary SQL queries via the ORDER BY clause to extract sensitive information from the database including user credentials, session tokens, and other confidential data through time-based blind SQL injection techniques.

Chamilo LMS is an open-source learning management system. In versions prior to 2.0.0-RC.3, an insecure direct object modification vulnerability in the PUT /api/users/{id} endpoint allows any authenticated user with ROLE_STUDENT to escalate their privileges to ROLE_ADMIN by modifying the roles field on their own user record. The API Platform security expression is_granted('EDIT', object) only verifies record ownership, and the roles field is included in the writable serialization group, enabling any user to set arbitrary roles such as ROLE_ADMIN. Successful exploitation grants full administrative control of the platform, including access to all courses, user data, grades, and administrative settings.

Chamilo LMS is an open-source learning management system. In versions prior to 2.0.0-RC.3, an OS Command Injection vulnerability exists in the main/inc/ajax/gradebook.ajax.php endpoint within the export_all_certificates action, where the course code retrieved from the session variable $_SESSION['_cid'] via api_get_course_id() is concatenated directly into a shell_exec() command string without sanitization or escaping using escapeshellarg(). If an attacker can manipulate or poison their session data to inject shell metacharacters into the _cid variable, they can achieve arbitrary command execution on the underlying server. Successful exploitation grants full access to read system files and credentials, alters the application and database, or disrupts server availability. This issue has been fixed in version 2.0.0-RC.3.

Chamilo LMS is an open-source learning management system. In versions prior to 2.0.0-RC.3, the /api/course_rel_users endpoint is vulnerable to Insecure Direct Object Reference (IDOR), allowing an authenticated attacker to modify the user parameter in the request body to enroll any arbitrary user into any course without proper authorization checks. The backend trusts the user-supplied input for the user field and performs no server-side verification that the requester owns the referenced user ID or has permission to act on behalf of other users. This enables unauthorized manipulation of user-course relationships, potentially granting unintended access to course materials, bypassing enrollment controls, and compromising platform integrity.

Chamilo LMS is an open-source learning management system. In versions prior to 2.0.0-RC.3, the notebook module contains an Insecure Direct Object Reference (IDOR) vulnerability that allows any authenticated student to read the private course notes of any other user on the platform by manipulating the notebook_id parameter in the editnote action. The application fetches the note content using only the supplied integer ID without verifying that the requesting user owns the note, and the full title and HTML body are rendered in the edit form and returned to the attacker's browser. While ownership checks exist in the write paths (updateNote() and delete_note()), they are entirely absent from the read path (get_note_information()).

Chamilo LMS is an open-source learning management system. In versions prior to 2.0.0-RC.3, a Stored Cross-Site Scripting (XSS) vulnerability exists in the social post attachment upload functionality, where an authenticated user can upload a malicious HTML file containing JavaScript via the /api/social_post_attachments endpoint. The uploaded file is served back from the application at the generated contentUrl without sanitization, content type restrictions, or a Content-Disposition: attachment header, causing the JavaScript to execute in the browser within the application's origin. Because the payload is stored server-side and runs in the trusted origin, an attacker can perform session hijacking, account takeover, privilege escalation (if an admin views the link), and arbitrary actions on behalf of the victim. This issue has been fixed in version 2.0.0-RC.3.

Chamilo LMS is an open-source learning management system. In versions prior to 2.0.0-RC.3, the PENS (Package Exchange Notification Services) plugin endpoint at public/plugin/Pens/pens.php is accessible without authentication and accepts a user-controlled package-url parameter that the server fetches using curl without filtering private or internal IP addresses, enabling unauthenticated Server-Side Request Forgery (SSRF). An attacker can exploit this to probe internal network services, access cloud metadata endpoints (such as 169.254.169.254) to steal IAM credentials and sensitive instance metadata, or trigger state-changing operations on internal services via the receipt and alerts callback parameters. No authentication is required to exploit either SSRF vector, significantly increasing the attack surface. This issue has been fixed in version 2.0.0-RC.3.

Chamilo LMS is an open-source learning management system. In version 2.0-RC.2, the file public/main/inc/ajax/install.ajax.php is accessible without authentication on fully installed instances because, unlike other AJAX endpoints, it does not include the global.inc.php file that performs authentication and installation-completed checks. Its test_mailer action accepts an arbitrary Symfony Mailer DSN string from POST data and uses it to connect to an attacker-specified SMTP server, enabling Server-Side Request Forgery (SSRF) into internal networks via the SMTP protocol. An unauthenticated attacker can also abuse this to weaponize the Chamilo server as an open email relay for phishing and spam campaigns, with emails appearing to originate from the server's IP address. Additionally, error responses from failed SMTP connections may disclose information about internal network topology and running services. This issue has been fixed in version 2.0.0-RC.3.

Apr 14, 2026Chamilo is an open-source learning management system (LMS).CVE-2026-33714 · Other software · chamilo · reported by GitHubHigh 7.1
Chamilo is an open-source learning management system (LMS). Version 2.0.0-RC.2 contains a SQL Injection vulnerability in the statistics AJAX endpoint, which is an incomplete fix for CVE-2026-30881. While CVE-2026-30881 was patched by applying Security::remove_XSS() to the date_start and date_end parameters in the get_user_registration_by_month action, the same parameters remain unsanitized in the users_active action within the same file (public/main/inc/ajax/statistics.ajax.php), where they are directly interpolated into a SQL query. An authenticated admin can exploit this to perform time-based blind SQL injection, enabling extraction of arbitrary data from the database. This issue has been fixed in version 2.0.0.

In Totara LMS v19.1.5 and before, the forgot password API does not implement rate limiting for the target email address. which can be used for an Email Bombing attack. NOTE: the Supplier's position is that the pwresettime configuration defaults to 30 minutes, the pwresettime configuration is a hard control enforced via flag PWRESET_STATUS_ALREADYSENT, and no further password-reset email messages are sent if this flag is active for a specific email address.

Totara LMS v19.1.5 and before is vulnerable to Incorrect Access Control. The login page code can be manipulated to reveal the login form. An attacker can chain that with missing rate-limit on the login form to launch a brute force attack. NOTE: this is disputed by the Supplier because (1) local login is enabled/disabled server side (this is not a client side control); (2) there is no evidence SSO login can be bypassed to allow local login; and (3) there is no evidence that local login can be performed when disabled server side.

Apr 11, 2026A Cross-site Scripting (XSS) vulnerability was identified in the `from_dict` method of the `AppLollmsMessage` class in parisneo/lollms prior to version 2.2.0.CVE-2026-1116 · Other software · parisneo · reported by security@huntr.devMedium 6.1
A Cross-site Scripting (XSS) vulnerability was identified in the `from_dict` method of the `AppLollmsMessage` class in parisneo/lollms prior to version 2.2.0. The vulnerability arises from the lack of sanitization or HTML encoding of the `content` field when deserializing user-provided data. This allows an attacker to inject malicious HTML or JavaScript payloads, which can be executed in the context of another user's browser. Exploitation of this vulnerability can lead to account takeover, session hijacking, or wormable attacks.

Apr 10, 2026LifterLMS: SQL InjectionCVE-2026-5207 · WordPress plugins & themes · reported by WordfenceMedium 6.5
The LifterLMS plugin for WordPress is vulnerable to SQL Injection via the 'order' parameter in all versions up to, and including, 9.2.1. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Instructor-level access and above who have the edit_post capability on the quiz, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Apr 10, 2026Tutor LMS – eLearning and online course solution: Insecure Direct Object ReferenceCVE-2026-3371 · WordPress plugins & themes · reported by WordfenceMedium 4.3
The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.9.7. This is due to missing authorization checks in the `save_course_content_order()` private method, which is called unconditionally by the `tutor_update_course_content_order` AJAX handler. While the handler's `content_parent` branch includes a `can_user_manage()` check, the `save_course_content_order()` call processes attacker-supplied `tutor_topics_lessons_sorting` JSON without any ownership or capability verification. This makes it possible for authenticated attackers with Subscriber-level access or above to detach lessons from topics, reorder course content, and reassign lessons between topics in any course, including admin-owned courses, by sending a crafted AJAX request with manipulated topic and lesson IDs.

Apr 10, 2026Tutor LMS – eLearning and online course solution: Unauthorized private course enrollmentCVE-2026-3358 · WordPress plugins & themes · reported by WordfenceMedium 5.4
The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized private course enrollment in all versions up to, and including, 3.9.7. This is due to missing post_status validation in the `enroll_now()` and `course_enrollment()` functions. Both enrollment endpoints verify the nonce, user authentication, and whether the course is purchasable, but fail to check if the course has a `private` post_status. This makes it possible for authenticated attackers with Subscriber-level access or above to enroll in private courses by sending a crafted POST request with the target course ID. The enrollment record is created in the database and the private course title and enrollment status are exposed in the subscriber's dashboard, though WordPress core access control prevents the subscriber from viewing the actual course content (returns 404). Enrollment in private courses should be restricted to users with the `read_private_posts` capability.

Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, REST API keys are generated using md5(time() + (user_id * 5) - rand(10000, 10000)). The rand(10000, 10000) call always returns exactly 10000 (min == max), making the formula effectively md5(timestamp + user_id*5 - 10000). An attacker who knows a username and approximate key creation time can brute-force the API key. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3.
