CVE-2025-58381

Directory escape via shell path-variable manipulation

Published Feb 3, 2026 · Updated Feb 3, 2026

Path traversal in the Fabric OS shell before 9.2.1c2 and in 9.2.2 through 9.2.2a allows local users to access other directories. The source, ping6, sleep, disown, and wait commands permit path-variable manipulation that escapes the intended directory hierarchy. Access to an authenticated admin shell is required, and the disclosed consequence is limited to reaching directories outside the intended path.
