medium Nessus Plugin ID 327417

Language:

Synopsis

The instance of JetBrains TeamCity installed on the remote host is affected by multiple vulnerabilities.

Description

The version of JetBrains TeamCity installed on the remote host is prior to 2026.1.2. It is, therefore, affected by multiple vulnerabilities:

 - In JetBrains TeamCity before 2026.1.2 arbitrary file access was possible via the Perforce VCS integration (CVE-2026-59793)

 - In JetBrains TeamCity before 2026.1.2 stored XSS on the cloud profile page was possible via agent-reported data (CVE-2026-59794)

 - In JetBrains TeamCity before 2026.1.2 stored XSS via unauthenticated agent registration was possible (CVE-2026-59795)

 - In JetBrains TeamCity before 2026.1.2 pipeline modification was possible due to improper permission checks (CVE-2026-59796)

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 TeamCity version 2026.1.2 or later.
