# GitPython: git-config section-name injection enables arbitrary config directives (core.sshCommand RCE)

Advisory record · `GHSA-3rp5-jjmw-4wv2`

- **Identifiers:** `GHSA-3rp5-jjmw-4wv2` · `CVE-2026-69097` · `PYSEC-2026-3981`
- **State:** Confirmed
- **Severity:** CVSS 7.3 High
- **Critical:** No
- **Weakness (CWE):** [CWE-74](https://cwe.mitre.org/data/definitions/74.html)
- **Tags:** [Other injection](https://agentprime.io/advisories/tag/injection.md)
- **Published:** 24 Jul 2026

- **Reviewed by a person:** No

Published by the GitHub Advisory Database at 24 Jul 2026, 16:22 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `gitpython` (PyPI): affected `<3.1.53`; fixed in `3.1.53`

## Machine-written summary

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

> GitPython versions before 3.1.53 are vulnerable to config section-name injection: section names are written into a git config header with only CR, LF and NUL filtered, so a name containing a closing bracket can inject an arbitrary config directive such as core.sshCommand. An attacker who can supply a submodule name, either through a cloned repository's .gitmodules file or through an application that lets users name submodules, can achieve remote code execution on the next git operation. Upgrade to GitPython 3.1.53 or later; the source gives no other workaround.

## 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-3rp5-jjmw-4wv2>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
