Data disclosure via missing TLS certificate validation
Published Nov 10, 2025 · Updated Feb 26, 2026
Improper certificate validation in JetBrains YouTrack before 2025.3.104432 allows remote authenticated users to obtain disclosed data. YouTrack's TLS certificate-validation path accepts an untrusted peer certificate instead of rejecting it, but JetBrains has not named the affected request path. Exploitation requires low-privileged access and control of the TLS peer or connection path; the documented consequence is data disclosure.
