Impact
Unauthenticated remote attackers can read internal OTRS application configuration data over the network. They get access to frontend routes, auth groups, and integration settings to assist in reconnaissance for further attacks.
Root cause
The OTRS Agent Frontend configuration endpoint fails to enforce authentication checks before returning internal configuration details.
Affected systems
OTRS 8.0.X, 2023.X, 2024.X, 2025.X, and 2026.X before 2026.7.X
CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Fix & remediation
Upgrade OTRS to version 2026.7.X or later. If upgrading immediately is not possible, restrict external network access to the Agent Frontend configuration endpoint at your reverse proxy or web application firewall.
AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
NVD description
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
