Summary
JetBrains YouTrack versions before 2026.2.19575, 2026.3.16075, 2026.3.16397 and 2026.3.16402 are affected. Mail rules lack an authorization check (CWE-862), which lets a project admin execute issue commands in other projects. An attacker needs a project admin account and no user interaction, and the impact is high confidentiality and integrity.
