Deeper analysis
CVE-2024-36373 is a stored cross-site scripting vulnerability (CWE-79) affecting JetBrains TeamCity versions prior to 2024.03.2. It resides in the handling of untrusted builds settings and carries a CVSS 3.1 base score of 4.6 reflecting network attack vector, low complexity, low required privileges, and required user interaction.
An authenticated attacker with low privileges can inject persistent malicious scripts through untrusted build configurations. When another user later views the affected settings, the script executes in that user's browser context, enabling limited theft of information or unauthorized actions within the TeamCity application.
The vendor advisory at https://www.jetbrains.com/privacy-security/issues-fixed/ identifies the issue and states that upgrading to TeamCity 2024.03.2 resolves the stored XSS flaws.
EPSS remains flat at 0.5624 with no material increase after disclosure.
