CVE-2025-54531

Directory escape via plugin unpacking

Published Jul 28, 2025 · Updated Feb 26, 2026

Relative path traversal in JetBrains TeamCity before 2025.07 allows local users to escape plugin unpacking directories on Windows. During plugin unpacking, a crafted relative path is not confined to the intended extraction directory; JetBrains has not published the affected routine or validation failure. Exploitation requires high privileges, user interaction, and a Windows host; the vendor has not disclosed the exact files reachable or resulting operations.
