# GitPython has Command Injection via Git options bypass

- **Identifiers:** `GHSA-rpm5-65cw-6hj4` · `CVE-2026-42215` · `PYSEC-2026-2160`
- **State:** Confirmed
- **Severity:** CVSS 8.8 High
- **Critical:** No
- **Weakness (CWE):** [CWE-78](https://cwe.mitre.org/data/definitions/78.html)
- **Tags:** [Command injection](https://agentprime.io/advisories/tag/command-injection.md)

- **Reviewed by a person:** No

Published by the GitHub Advisory Database at 25 Apr 2026, 23:42 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `gitpython` (PyPI): affected `>=3.1.30, <3.1.47`; fixed in `3.1.47`

## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> GitPython versions from 3.1.30 before 3.1.47 are affected. The unsafe-option guard blocks options such as upload-pack and receive-pack but not their underscore spellings (upload_pack and receive_pack) passed as Python keyword arguments to clone_from, fetch, pull, or push. If an application passes attacker-controlled keyword arguments into these calls, an attacker can run arbitrary commands as the application's account, even with allow_unsafe_options left at its default. Upgrade to GitPython 3.1.47 or later; no other workaround is listed.

## Check whether this affects you

A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet.

- With the agentprime MCP server (<https://api.agentprime.io/mcp>), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: <https://agentprime.io/mcp.md>
- In a browser: <https://agentprime.io/check/> reads your lockfile in the browser, never uploading it.
- Whether it touches your code, with file and line: the Claude Code plugin, <https://agentprime.io/plugin.md>
- As JSON: <https://api.agentprime.io/v1/advisories/GHSA-rpm5-65cw-6hj4>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
