JetBrains TeamCity < 2025.11.3 Multiple Vulnerabilities

medium Nessus Plugin ID 300067

Language:

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of JetBrains TeamCity installed on the remote host is prior to 2025.11.3. It is, therefore, affected by multiple vulnerabilities:

 - Open redirect was possible in the React project creation flow. (CVE-2026-28194)

 - Missing authorization allowed project developers to add parameters to build configurations. (CVE-2026-28195)

 - Disabling versioned settings left a credentials config on disk. (CVE-2026-28196)

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 2025.11.3 or later.
