Technical details

A code injection vulnerability (CWE-94) exists in JetBrains TeamCity's Git Version Control System (VCS) root configuration. The flaw allows an attacker with high-level administrative privileges to execute arbitrary code on the TeamCity server by manipulating Git VCS root settings. The vulnerability is reachable over the network without user interaction, though it requires 'High' privileges (PR:H). Successful exploitation results in a scope change (S:C), potentially allowing the attacker to move beyond the TeamCity application to the underlying host system. The issue is fixed in versions 2026.1.2 and 2025.11.6.
