Ecosystem-wide dependent count for version 3.1.53.

DescriptionCVE.org

GitPython before 3.1.53 fails to properly escape section names in git config files, allowing attackers to inject arbitrary configuration directives through malicious submodule names. Attackers can inject core.sshCommand or other dangerous config keys into the victim's .git/config via create_submodule or clone_from operations, achieving remote code execution when git performs ssh operations.

AnalysisAI

Git-config section-name injection in GitPython <= 3.1.52 enables remote code execution by writing attacker-controlled core.sshCommand directives into a victim's .git/config via the create_submodule() or clone_from() API methods. The vulnerable component (CPE: cpe:2.3:a:gitpython-developers:gitpython) fails to escape bracket characters in submodule names, allowing a crafted name such as x"] [core] sshCommand=malicious # to close the intended config section header and open a new one on the same line - bypassing the existing CR/LF/NUL guard entirely. No public exploit has been identified at time of analysis and no CISA KEV listing exists, but the fully documented injection mechanism and RCE primitive make this a high-priority fix for any pipeline processing untrusted repositories.

Technical ContextAI

GitPython is a Python library for programmatic git repository interaction, identified by CPE cpe:2.3:a:gitpython-developers:gitpython:*:*:*:*:*:*:*:*. Git's native config file format uses [section "subsection"] headers where the section name is delimited by [ and ]. GitPython's _assure_config_name_safe() function in git/config.py line 75 enforces only a regex guard r'[\r\n\x00]' - stripping CR, LF, and NUL - before writing names verbatim into the [%s]\n header template at line 693. For submodules, git/objects/submodule/util.py:39 wraps the attacker-supplied name as submodule "<name>". A name containing "] [core] sshCommand=CMD # causes the serialized line to become [submodule "x"] [core] sshCommand=CMD #"], which git's config parser interprets as two distinct sections: the intended submodule entry and a new [core] block setting sshCommand. This is CWE-74 (Injection) - specifically an incomplete output-encoding failure that was previously partially addressed for newline injection in 3.1.50 (GHSA-mv93-w799-cj2w, GHSA-v87r-6q3f-2j67) but left same-line bracket injection unmitigated. Beyond core.sshCommand, the same primitive can inject core.fsmonitor, core.pager, and alias.* directives.

RemediationAI

Upgrade GitPython to version 3.1.53 or later using pip install --upgrade gitpython. This is a vendor-released patch confirmed by the GHSA advisory and the fix commit at https://github.com/gitpython-developers/GitPython/commit/1ed1b924f4e2d2ee7bab296df77b978af21853f1. The full vendor advisory is at https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-3rp5-jjmw-4wv2. As a compensating control prior to patching, applications should validate submodule names before passing them to create_submodule() or clone_from(), rejecting any names containing ], [, ", #, =, or whitespace - note this may break legitimate submodule names containing these characters. Additionally, avoid cloning or processing repositories from untrusted sources until patched, since .gitmodules contents directly feed the vulnerable code paths. Pipelines that cannot immediately upgrade should consider disabling submodule initialization (--no-recurse-submodules) as a temporary measure, accepting the trade-off of broken submodule functionality.
