CVE-2026-49374: CWE-862 in JetBrains TeamCity
In JetBrains TeamCity before 2026.1 improper permission checks exposed build configuration parameters
AI Analysis
Technical Summary
This vulnerability in JetBrains TeamCity prior to version 2026.1 arises from improper permission checks (CWE-862) that expose build configuration parameters to users who should not have access. The CVSS 3.1 base score is 7.6, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, and high confidentiality impact with lower integrity and availability impacts. No official patch or remediation guidance has been published by JetBrains as of the publication date.
Potential Impact
An attacker with limited privileges can access sensitive build configuration parameters that should be restricted, potentially leading to unauthorized disclosure of confidential information. The impact includes high confidentiality loss, with some impact on integrity and availability of the build configurations. No known exploitation in the wild has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the JetBrains advisory for current remediation guidance. Until an official fix is released, restrict access to TeamCity instances to trusted users only and monitor for unusual access patterns related to build configuration parameters.
