CVE-2026-67324

Description

A flaw was found in GitPython. A remote attacker can exploit a vulnerability where the software fails to properly recognize joined short-option forms (e.g., -u) when enforcing its default unsafe-option gate. This allows the attacker to bypass security checks and execute arbitrary commands during a Git clone operation. This can lead to a complete compromise of the affected system.

Statement

This vulnerability is rated as Important because exploitation requires an application to invoke Repo.clone_from() with attacker-controlled multi_options while allow_unsafe_options=False is set. This precondition means an attacker must already have some influence over a Git-related workflow within the consuming application, rather than exploiting it through mere network access. This affects GitPython version 3.1.50.

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.

Understanding the Weakness (CWE)

Confidentiality,Integrity,Availability,Non-Repudiation

Technical Impact: Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart; Read Files or Directories; Modify Files or Directories; Read Application Data; Modify Application Data; Hide Activities

Attackers could execute unauthorized operating system commands, which could then be used to disable the product, or read and modify data for which the attacker does not have permissions to access directly. Since the targeted application is directly executing the commands instead of the attacker, any malicious activities may appear to come from the application or the application's owner.
