CVE-2025-41390Public exploitHinoki check available

Arbitrary code execution via untrusted fsmonitor configuration

Published Oct 20, 2025 · Updated Oct 20, 2025

Code execution in Truffle Security TruffleHog 3.90.2 allows attackers to run commands by scanning a crafted local Git repository. The Git scanner invokes the Git client with repository-local configuration enabled, causing Git to execute a command supplied through core.fsmonitor in .git/config. Exploitation requires a user or automation to scan a repository copied file-for-file rather than cloned, after which commands run with the scanner process's privileges.
