CVE-2024-36373Network attack vector

Browser script execution via untrusted build settings

Published May 29, 2024 · Updated Aug 2, 2024

Stored XSS in JetBrains TeamCity before 2024.03.2 allows remote authenticated users to execute script in a user's browser. Untrusted build-setting values are persisted and later rendered without effective script neutralization, although JetBrains has not identified the affected fields or rendering code. Exploitation requires low-privileged access to save a crafted setting and user interaction to view it, enabling browser-context data access or actions.
