CVE-2025-54533Network attack vector

Build-settings disclosure via VCS configuration

Published Jul 28, 2025 · Updated Jul 28, 2025

Improper access control in JetBrains TeamCity before 2025.07 allows attackers to disclose build settings through VCS configuration. JetBrains has not published the concrete code locus or the operation that fails to enforce authorization when VCS configuration is accessed. Public sources do not specify required privileges or which setting values are exposed, so the bounded consequence is build-settings disclosure.
