CVE-2026-73624
Description
A flaw was found in GitPython. This vulnerability allows a remote attacker to overwrite arbitrary files on the system. By failing to properly validate git options passed to the Diffable.diff method, an attacker can supply a malicious output argument to write patch content to attacker-controlled file paths, leading to potential system compromise.
Statement
This is an Important arbitrary file overwrite vulnerability in GitPython's Diffable.diff method. It allows an attacker to write arbitrary content to chosen file paths at the process's privilege level by manipulating git options, which could lead to system compromise or privilege escalation.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
