AI Analysis
Technical Summary
This vulnerability in JetBrains TeamCity versions prior to 2026.1 involves improper handling of Perforce connection settings that can be exploited to achieve remote code execution. The CVSS v3.1 base score is 7.1, reflecting a network attack vector with low attack complexity and no user interaction required. The attacker needs low privileges to exploit this issue. The vulnerability is categorized as CWE-88, indicating command injection or improper neutralization of commands. No official patch or remediation guidance has been published by JetBrains at this time.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker with low privileges to execute arbitrary code remotely on the affected TeamCity server. This could lead to unauthorized access to sensitive information (high confidentiality impact) but is assessed to have limited impact on integrity and no impact on availability. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or temporary mitigation has been published by JetBrains, users should monitor JetBrains advisories for updates. Until a patch is available, restricting access to TeamCity and limiting privileges for users who can configure Perforce connections may reduce risk.
