Detailsinfo

A vulnerability classified as critical has been found in gitpython-developers GitPython up to 3.1.53. Affected is the function clone_from/fetch/pull/push/ls_remote/iter_commits/blame/archive of the component check_unsafe_options. The manipulation of the argument upload-pack with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

GitPython versions before 3.1.54 contain a remote code execution vulnerability in the check_unsafe_options guard that can be bypassed by smuggling git options inside single-character kwarg values. Attackers can supply crafted option dictionaries to clone_from, fetch, pull, push, ls_remote, iter_commits, blame, or archive methods to execute arbitrary OS commands via the --upload-pack parameter.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-73625 since 08/13/2026. The exploitability is told to be easy. It is possible to launch the attack remotely.
