CVE-2026-59793Network attack vector

Authenticated arbitrary file access via Perforce integration

Published Jul 10, 2026 · Updated Jul 10, 2026

External control of file paths in JetBrains TeamCity before 2026.1.2 allows remote authenticated users to access arbitrary files. The affected locus is the Perforce VCS integration, but JetBrains has not disclosed which path value is attacker-controlled or which filesystem operation consumes it. Exploitation requires a low-privileged authenticated account, network reachability, and a configured Perforce integration; file reach is bounded by server-process permissions.
