Oct 12, 2026The HTTP Basic Authentication modules in ((OTRS)) Community Edition 6 and prior accept the authenticated username from either the REMOTE_USER or HTTP_REMOTE_USECVE-2026-93582 · Other software · OTRS GmbH (former OTRS AG) · reported by security@otrs.comCritical 9.4
The HTTP Basic Authentication modules in ((OTRS)) Community Edition 6 and prior accept the authenticated username from either the REMOTE_USER or HTTP_REMOTE_USER environment variable. In CGI and mod_perl based deployments, HTTP request headers may be mapped to corresponding HTTP_* environment variables. As a result, an unauthenticated remote attacker can supply a crafted Remote-User request header which is exposed to the application as HTTP_REMOTE_USER. When HTTP Basic Authentication is configured as the authentication backend, OTRS trusts this value as an already authenticated username and does not perform an additional password verification. An attacker may therefore authenticate through the Generic Interface as an existing agent or customer user without knowing the corresponding credentials. The resulting privileges depend on the account being impersonated. Successful exploitation may allow access to confidential information and modification of data or configuration with the permissions of the affected user. Exploitation requires HTTP Basic Authentication to be configured as an authentication backend and a web server environment in which attacker-controlled HTTP headers are exp

Oct 12, 2026User-controlled values are not sufficiently neutralized when included in CSV exports.CVE-2026-93581 · Other software · OTRS GmbH (former OTRS AG) · reported by security@otrs.comMedium 6.1
User-controlled values are not sufficiently neutralized when included in CSV exports. Values originating from user input, including data submitted by authenticated users or received through external communication channels such as email, may be stored in fields that are later included in CSV exports. An attacker can therefore inject values beginning with spreadsheet formula characters such as =, +, -, or @. An attacker does not necessarily require an authenticated account if the affected field can be populated through an external input channel such as incoming email. When an affected CSV file is opened in spreadsheet software, the application may interpret these values as formulas instead of plain text. Depending on the spreadsheet application and its security configuration, a malicious formula may cause unintended actions, disclose information, or invoke external functionality. Exploitation may require the user opening the exported CSV file to confirm one or more security warning dialogs. The vulnerability does not execute code on the OTRS server; any additional impact occurs in the spreadsheet application used to process the exported file. This issue affects OTRS: * 7.0.X

Oct 12, 2026OTRS does not sufficiently enforce the uniqueness of customer user identities across multiple configured CustomerUser backends.CVE-2026-78359 · Other software · OTRS GmbH (former OTRS AG) · reported by security@otrs.comMedium 5.4
OTRS does not sufficiently enforce the uniqueness of customer user identities across multiple configured CustomerUser backends. When multiple backends, such as a database and LDAP, are configured, the uniqueness check for customer user email addresses is performed only within the selected backend. As a result, an authenticated user with permission to create or modify customer users may create a customer user whose email address is already assigned to a customer user in another backend. This can result in multiple customer user records representing the same communication identity. Depending on the affected workflow and backend resolution, customer-related information or email communication may subsequently be associated with or exposed to the wrong customer user. The vulnerability does not allow unauthenticated users to create customer accounts. Exploitation requires permissions to create or modify customer users. This issue affects OTRS: * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.7.X Please note that ((OTRS)) Community Edition 6.x and before are vulnerable.

Oct 12, 2026Several administrative actions do not sufficiently validate whether a request was intentionally initiated by the authenticated user.CVE-2026-78358 · Other software · OTRS GmbH (former OTRS AG) · reported by security@otrs.comMedium 4.3
Several administrative actions do not sufficiently validate whether a request was intentionally initiated by the authenticated user. In particular, the DBUpdateLogCleanUp action can be triggered through a GET request without validating a ChallengeToken. An unauthenticated remote attacker can therefore cause the browser of an authenticated administrator to execute the cleanup action by embedding a crafted request in a malicious web page. Successful exploitation can delete existing DBUpdate log entries. This may reduce the availability of diagnostic and historical information used for troubleshooting and auditing. The impact is limited to DBUpdate log entries that exist at the time the forged request is processed. Additional administrative endpoints were identified that do not validate a ChallengeToken. Some of these endpoints can trigger administrative actions such as deploying or synchronizing already existing configuration. They do not allow an attacker to introduce arbitrary new configuration through the CSRF request itself. Export and read-only endpoints were also identified without ChallengeToken validation. While these endpoints may be triggered through a forged cross-site

Oct 12, 2026Previously issued authentication tokens are not immediately invalidated when an OTRS agent or customer user account is deactivated or its password is changed.CVE-2026-78357 · Other software · OTRS GmbH (former OTRS AG) · reported by security@otrs.comCritical 9.1
Previously issued authentication tokens are not immediately invalidated when an OTRS agent or customer user account is deactivated or its password is changed. As a result, an existing JWT may remain valid until its regular expiration time, which can be approximately 16 hours. An attacker who has previously obtained a valid authentication token can therefore continue to access OTRS with the privileges of the affected agent or customer user even after the corresponding account has been deactivated or the user's password has been changed. The vulnerability does not allow an attacker to obtain authentication tokens by itself. Exploitation requires possession of a previously issued and still valid token. The actual impact depends on the privileges associated with the compromised token. Customer user tokens are limited to the permissions of the affected customer account, while agent tokens may provide access to broader ticket, customer, or administrative functionality depending on the assigned permissions. This issue affects OTRS: * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.7.X

Oct 12, 2026The OTRS Agent Frontend configuration endpoint can be accessed without authentication.CVE-2026-78356 · Other software · OTRS GmbH (former OTRS AG) · reported by security@otrs.comMedium 5.3
The OTRS Agent Frontend configuration endpoint can be accessed without authentication. This allows unauthenticated remote users to retrieve internal application configuration that is intended for use by the authenticated Agent Frontend. The exposed information may include configured frontend routes and their associated authorization groups, authentication configuration, enabled product features, third-party integration settings, and other implementation details. The exposed configuration does not directly contain user credentials or provide unauthorized modification of the OTRS configuration. However, the disclosed information may assist an attacker in fingerprinting the affected OTRS installation and identifying enabled functionality or security-relevant configuration that could be used to prepare further attacks. This issue affects OTRS: * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.7.X

A path traversal vulnerability in the OTRS SendSupportBundle functionality allows an authenticated administrator to reference file paths outside the intended directory. This may allow files accessible to the OTRS application process to be deleted. The vulnerability does not bypass operating system file permissions. On OTRS versions prior to OTRS 7, the effective permissions of the web server process are relevant. Starting with OTRS 7, access is limited by the permissions of the dedicated OTRS user. Files with overly permissive ownership or file system permissions may therefore also be affected. The affected functionality may additionally attempt to include controlled files in a support bundle. However, support bundles are sent to a predefined OTRS support address, and direct disclosure of arbitrary files to the attacker has not been demonstrated. An attacker therefore requires valid administrative access to exploit the vulnerable functionality. The primary demonstrated impact is the deletion of files outside the intended directory within the effective permissions of the OTRS application process. This issue affects OTRS: * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X
