Deeper analysis
The vulnerability CVE-2024-36370 is a stored cross-site scripting flaw (CWE-79) present in JetBrains TeamCity releases before 2022.04.7, 2022.10.6, 2023.05.6, and 2023.11.5. It resides in the handling of OAuth connection settings and carries a CVSS 3.1 score of 4.6.
An authenticated user with low privileges can supply crafted OAuth configuration values that are persisted on the server. When other users later view the affected settings pages, the malicious script executes in their browsers under the application origin, enabling limited theft of session data or unauthorized actions that require user interaction.
JetBrains has published fixes in the listed maintenance releases; administrators are advised to upgrade TeamCity instances to one of the patched versions referenced in the vendor’s security advisory pages.
The associated EPSS score rose from a low baseline to a peak of 0.5080 on 2026-02-26 before receding to the current value of 0.4581, indicating measurable post-disclosure exploitation interest.
