AI Analysis
Technical Summary
This vulnerability affects JetBrains TeamCity prior to version 2026.1 and allows authenticated users to expose the server API to unauthorized access, representing a missing authentication control for critical functions (CWE-306). The CVSS 3.1 base score of 8.2 reflects a network attack vector with low attack complexity, no privileges required, and no user interaction needed. The impact primarily affects confidentiality (high), with limited integrity impact and no availability impact. No patch or official remediation level has been disclosed by JetBrains as of the publication date.
Potential Impact
The vulnerability allows authenticated users to bypass authentication controls and expose the server API to unauthorized access, potentially leading to unauthorized disclosure of sensitive information. The confidentiality impact is high, while integrity impact is limited and availability is unaffected. This could compromise sensitive data managed by TeamCity servers if exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict authenticated user privileges to minimize exposure and monitor for unusual API access patterns. Avoid exposing TeamCity servers to untrusted networks where possible.
