CVE-2024-31138Network attack vector

Stored script execution via Agent Distribution settings

Published Mar 28, 2024 · Updated Aug 2, 2024

Stored cross-site scripting in Agent Distribution settings in JetBrains TeamCity before 2024.03 allows remote authenticated users to inject script. JetBrains identifies the settings surface but has not published the affected field, storage path, or rendering operation that fails to neutralize input. An authenticated user must save crafted content and another user must view the affected interface, allowing script execution in that viewer's TeamCity session.
