The ShopMagic – email automation for WordPress plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.9.0 via the 'billing_address.first_name' parameter parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included. Exploitation requires a published recipe that processes the {{ customer.first_name }} placeholder — the plugin's built-in "New Order email with social media profile links" recipe satisfies this requirement out of the box, making the default configuration exploitable with no account, cookie, or nonce by simply submitting a guest checkout with the payload as the billing first name.

Oct 13, 2026Bit integrations – Form Integration, Webhook, Spreadsheets, CRM, LMS & Email Automation: Privilege EscalationCVE-2026-104749 · WordPress plugins & themes · reported by WordfenceHigh 7.5
The Bit integrations – Form Integration, Webhook, Spreadsheets, CRM, LMS & Email Automation plugin for WordPress is vulnerable to Privilege Escalation via Log Re-execution in all versions up to, and including, 2.10.6 The vulnerability exists because `IntegrationHandler::executeWithCapture()` stores raw, attacker-controlled field values — including `user_pass` and `user_email` — verbatim into `wp_btcbi_log.field_data` on anonymous front-end requests with no capability check, and `LogHandler::reexecute()` feeds that stored payload back through `Flow::execute()` inside the replaying administrator's session without validating the identity that originally produced the data, causing `RegistrationController::updateUser()` to resolve the target user ID to the administrator and write the attacker-supplied password via `wp_update_user()`. This makes it possible for unauthenticated attackers to overwrite the administrator's password and fully take over the administrator account. Exploitation requires that an administrator has configured a flow mapping a user-supplied form field to the `user_pass` parameter of the WP User Registration "Update User" action, and that the administrator subsequent

A vulnerability has been identified regarding insufficient validation in the Frappe Cloud/ERPNext authentication process, which allows multiple email addresses to be accepted by manipulating the email field in the /api/method/press.api.account.signup endpoint. The vulnerability occurs when an unauthenticated remote attacker adds more than one email address. The service processes the entire value as a valid list of recipients and sends the OTP code to all addresses without proper validation of all added emails (only one of them needs to be valid). Exploiting this vulnerability would allow an attacker to: * Obtain the authentication OTP; * Impersonate someone else in the registration process; * Register accounts using other people's email addresses without access to the mailbox; * Indirectly confirm the existence of already registered email addresses.

Oct 7, 2026Authenticated users are able to manipulate both the SMTP envelope “Envelope-from” and “From” fields when sending emails through OVH mail servers.CVE-2026-33586 · Other software · OVHcloud · reported by a6d3dc9e-0591-4a13-bce7-0f5b31ff6158Medium 6.3
Authenticated users are able to manipulate both the SMTP envelope “Envelope-from” and “From” fields when sending emails through OVH mail servers. Due to OVH's default SPF configuration, which commonly includes include:mx.ovh.com, any authenticated user with a valid OVH email account can send messages that appear to originate from any OVH-hosted domains using the default SPF record. Since the SPF policy explicitly authorizes OVH mail servers (mx.ovh.com) to send mail on behalf of these domains, forged messages successfully pass SPF validation despite not being authorized by the impersonated domain owner.

Oct 7, 2026MISP contains a race condition in the email-based one-time password (OTP) login flow.CVE-2026-107276 · Other software · MISP · reported by 5a6e4751-2f3f-4070-9419-94fb35b644e8Medium 6.3
MISP contains a race condition in the email-based one-time password (OTP) login flow. When two HTTP requests carrying the same valid OTP are submitted concurrently, both can successfully authenticate and establish a session. The root cause is that the OTP value is read from the shared store, validated, and then deleted in separate non-atomic steps, allowing a second in-flight request to read the same value before the first request's deletion takes effect. Preconditions: - The target MISP instance has email OTP login enabled. - The attacker possesses a valid, unexpired OTP (e.g., via email interception or social engineering). - The attacker can issue two HTTP POST requests in close temporal proximity. Impact: - The one-time-use guarantee of the OTP is violated; a single code can yield two authenticated sessions. - This weakens the authentication control and may facilitate unauthorized access if the OTP is shared or intercepted. Affected versions: <2.5.48

Oct 6, 2026Post SMTP – Complete Email Deliverability and SMTP Solution with Email Logs, Alerts, Backup SMTP & Mobile App: Stored Cross-Site ScriptingCVE-2026-75962 · WordPress plugins & themes · reported by WordfenceHigh 7.2
The Post SMTP – Complete Email Deliverability and SMTP Solution with Email Logs, Alerts, Backup SMTP & Mobile App plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'user_email' parameter in all versions up to, and including, 4.0.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable without authentication on WordPress Multisite installations with public registration enabled, as WordPress accepts email addresses containing numeric HTML character references that Post SMTP's stricter validator rejects, persisting the attacker-controlled address verbatim to the email log via the failed-send exception message.

The Newsletter – Send awesome emails from WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'np1' Custom Field Parameter in all versions up to, and including, 9.4.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The subscription endpoint (na=sa) requires no nonce, no capability check, and no CAPTCHA, and the payload can be smuggled past email-address validation by embedding the {profile_1} placeholder in the local part of the submitted address, since WordPress's is_email() permits curly braces there.

Sep 30, 2026Newsletter – Send awesome emails from: Insufficiently Protected CredentialsCVE-2026-92537 · WordPress plugins & themes · reported by WordfenceMedium 5.3
The Newsletter – Send awesome emails from WordPress plugin for WordPress is vulnerable to Insufficiently Protected Credentials in all versions up to, and including, 9.3.9 The plugin's public click-tracking REST route `/tnp/l/` is registered with `permission_callback => '__return_true'` and, upon receiving a valid keyed-MD5 signature, calls `set_user_cookie()`, which emits a `Set-Cookie: newsletter=<id>-<raw_token>` response header to the requester because the subscriber object loaded via `get_user()` lacks the `_trusted` property, causing `get_user_key()` to return the raw token column value instead of its MD5-masked variant. This makes it possible for unauthenticated attackers who obtain any signed click-tracking URL for a target subscriber to receive that subscriber's permanent raw authentication cookie, which they can then use to export the subscriber's full PII record via the JSON profile-export endpoint (`?na=px`), rewrite the subscriber's stored profile (`?na=ps`), and silently unsubscribe the subscriber via the RFC-8058 one-click endpoint (`?na=ocu`), none of which require a nonce, password, or email challenge. Signed tracking URLs are embedded in every external link of ever
