AI Analysis
Technical Summary
CVE-2026-65907 is a code execution vulnerability in JetBrains TeamCity affecting Git VCS roots. Versions before 2026.1.2 and 2025.11.6 are vulnerable. The vulnerability is classified as CWE-94 (Improper Control of Generation of Code), which can lead to arbitrary code execution. The CVSS v3.1 base score is 9.1, reflecting network attack vector, low attack complexity, high privileges required, no user interaction, and complete impact on confidentiality, integrity, and availability. No official remediation level or patch information is provided in the available data.
Potential Impact
Successful exploitation could allow an attacker with high privileges to execute arbitrary code on the TeamCity server via Git VCS roots. This compromises confidentiality, integrity, and availability of the affected system. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the JetBrains vendor advisory for current remediation guidance. Since no official fix or remediation level is provided, users should monitor JetBrains advisories closely and apply updates once available. Until then, restrict access to TeamCity instances and limit privileges to trusted users to reduce risk.
