CVE-2026-44231: Bestpractical Request Tracker

Critical severity, CVSS 9.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Bestpractical Request Tracker: before 5.0.10 (fixed in 5.0.10); from 6.0.0, before 6.0.3 (fixed in 6.0.3)
