JetBrains YouTrack < 2026.2.19562 Multiple Vulnerabilities

high Nessus Plugin ID 379539

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of JetBrains YouTrack installed on the remote host is prior to 2026.2.19562. It is, therefore, affected by multiple vulnerabilities:

 - In JetBrains YouTrack before 2026.2.19562 missing authorization in the saved query endpoint allowed disclosure of issue descriptions. (CVE-2026-123327)

 - In JetBrains YouTrack before 2026.2.19562 information disclosure via shared mailbox message history was possible. (CVE-2026-123324)

 - In JetBrains YouTrack before 2026.2.19562 missing authorization allowed Project Admin to manage VCS hosting server configurations. (CVE-2026-123332)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to JetBrains YouTrack version 2026.2.19562, or later.
