CVE-2024-24936Network attack vector

Artifact disclosure via missing endpoint authorization

Published Feb 6, 2024 · Updated Aug 1, 2024

Improper authorization in TeamCity before 2023.11.2 allows remote authenticated users to read S3-hosted build artifacts. The S3 Artifact Storage plugin endpoint omits an access-control check before serving artifact content requested by a logged-in user. Any low-privileged TeamCity account can reach data outside its authorized project scope; no integrity or availability impact is reported.
