CVE-2025-68267Network attack vector

Excess GitHub access via personal token storage

Published Dec 16, 2025 · Updated Dec 16, 2025

Least-privilege violation in JetBrains TeamCity before 2025.11.1 allows remote attackers to access GitHub with excessive permissions. The GitHub integration stores a user's personal access token where an installation token with narrower privileges should be stored. A configured GitHub connection is required, and the resulting access is limited to the repositories and operations permitted by that personal access token.
