Description

goose is general-purpose AI agent that runs on your machine. Prior to 1.44.0, the `goose review` command runs the system `git` executable to gather the diff for review without stripping attacker-controlled Git configuration. A malicious repository whose `.git/config` sets [`core] fsmonitor = <command>` causes Git to execute that command on the host during the index refresh performed by `git diff HEAD`. The command runs before goose contacts a model and without a submitted prompt, model call, tool approval, or trust prompt. The context-gathering Git process is not sandboxed and is outside goose's tool-permission model. Arbitrary commands run with the privileges and environment of the user running goose, allowing file access or modification and exfiltration of environment secrets and provider API keys. The vulnerable Git invocations are built by git_command() in crates/goose-cli/src/commands/review/handler.rs and are used by touched_files() and collect_diff() for `git diff --name-only HEAD` and `git diff HEAD`. This issue is fixed in version 1.44.0.

Executive Summary

The vulnerability in goose AI agent before version 1.44.0 allows malicious Git repositories to execute arbitrary commands on the host system. This happens because the goose review command uses the system Git executable to gather diffs without sanitizing attacker-controlled Git configuration. Specifically, a malicious .git/config file can set core.fsmonitor to run arbitrary commands during Git's index refresh, which occurs before any user interaction or model interaction in goose.

Detection Guidance

Check the version of goose installed on your system. If it is below 1.44.0, the vulnerability is present. Run: goose --version. If the output shows a version lower than 1.44.0, update goose immediately.

Impact Analysis

This vulnerability allows attackers to run any command on your machine with the same privileges as the user running goose. This could lead to file access or modification, theft of sensitive data like environment secrets or provider API keys, and potential compromise of your system or data.

Mitigation Strategies

Upgrade goose to version 1.44.0 or later. Avoid running goose in untrusted directories or with untrusted repositories. Review Git configurations in repositories to ensure no malicious core.fsmonitor settings are present.
