high Nessus Plugin ID 379540

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of JetBrains YouTrack installed on the remote host is prior to 2025.3.170763, or 2026.1.x prior to 2026.1.14150, or 2026.2.x prior to 2026.2.19656. It is, therefore, affected by multiple vulnerabilities:

 - In JetBrains YouTrack before 2025.3.170763, 2026.1.14150, 2026.2.19656 inclusion of untrusted remote code was possible via the plugin sandbox page. (CVE-2026-123325)

 - In JetBrains YouTrack before 2025.3.170763, 2026.1.14150, 2026.2.19656 improper URL validation in the app widget host allowed apps to send REST requests without user confirmation. (CVE-2026-123323)

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 2025.3.170763, 2026.1.14150, 2026.2.19656, or later.
