CVE-2022-42906

Arbitrary code execution via repository-controlled fsmonitor

Published Oct 13, 2022 · Updated May 15, 2025

Command injection in Powerline Gitstatus before 1.3.2 allows attackers to execute arbitrary code through a malicious Git repository. GitStatusSegment.get_base_command invokes Git without overriding repository-controlled core.fsmonitor, allowing Git to execute an attacker-supplied command. Exploitation requires a user to enter an attacker-controlled repository directory, after which commands run with that user's privileges.
