CVE-2026-44231: RT Issue Tracker: Privileged User Can Steal Admin Credentials
CVE-2026-44231
Summary
RT's issue and ticket tracking system has a security flaw that allows a non-admin user to steal admin passwords and use them to access sensitive data. This happens when a user requests a specific type of data, which also exposes the admin passwords. The passwords are then changed, making previously shared links to the data useless. To fix this, update to RT version 5.0.10 or 6.0.3.

Original description
RT is an open source, enterprise-grade issue and ticket tracking system. Versions prior to 5.0.10, 6.0.0 and above, prior to 6.0.3 contain an information disclosure and privilege escalation vulnerability in the REST 2.0 API. A privileged (non-administrative) user can obtain authentication credentials belonging to other users — including users with administrative privileges — and use those credentials to read data as those users via RT's feed endpoints. The same request that exposes the credentials also rotates them, invalidating previously-distributed feed URLs across the instance. This issue has been fixed in versions 5.0.10 and 6.0.3.
