Summary

Request Tracker (RT) 4.x before 4.0.25, 4.2.x before 4.2.14, and 4.4.x before 4.4.2 does not use a constant-time comparison algorithm for secrets, which makes it easier for remote attackers to obtain sensitive user password information via a timing side-channel attack.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
