RUSTSEC-2025-0139: theshit vulnerable to unsafe loading of user-owned Python rules when running as root

What to do

1. See which version you have: cargo tree -i theshit (it also shows which of your dependencies pulls it in).
2. Update within your version requirement: cargo update -p theshit. If the fix is a newer major or minor than your requirement allows, raise it in Cargo.toml (for example theshit = "0.1.1") or update the dependency that pulls it in.
3. Check again with cargo audit, or paste your Cargo.lock into our Cargo.toml checker.

Details from the advisory

The application loads custom Python rules and configuration files from user-writable locations (e.g., ~/.config/theshit/) without validating ownership or permissions when executed with elevated privileges.

If the tool is invoked with sudo or otherwise runs with an effective UID of root, it continues to trust configuration files originating from the unprivileged user's environment. This allows a local attacker to inject arbitrary Python code via a malicious rule or configuration file, which is then executed with root privileges.

The patch introduces strict ownership and permission checks for all configuration files and custom rules. The application now enforces that rules are only loaded if they are owned by the effective user executing the tool.

When executed with elevated privileges (EUID=0), the application refuses to load any files that are not owned by root or that are writable by non-root users. When executed as a non-root user, it similarly refuses to load rules owned by other users. This prevents both vertical and horizontal privilege escalation via execution of untrusted code.
