CVE-2024-56350Network attack vector

Cross-project disclosure via overprivileged build credentials

Published Dec 20, 2024 · Updated Dec 20, 2024

Incorrect authorization in JetBrains TeamCity before 2024.12 allows remote authenticated users to view projects outside their permissions. Build-level authentication parameters are accepted for project access without enforcing the credential holder's authorized project scope. The user must hold the View build configuration settings permission; impact is limited to reading otherwise unauthorized project data.
