CVE-2026-73622

Description

A flaw was found in GitPython. This vulnerability allows a remote attacker to exfiltrate sensitive information, such as environment variables, by crafting malicious URLs. When these URLs are processed during Git operations like fetch or pull, the environment variables are expanded and transmitted to attacker-controlled hosts, leading to information disclosure.

Statement

This is an Important information disclosure flaw in GitPython. It allows an attacker to exfiltrate sensitive environment variables from systems that use GitPython to create or add remote repositories from untrusted URLs. This occurs because environment variable expansion is not disabled in URL handling, leading to secrets being embedded in Git configuration and transmitted to attacker-controlled hosts.

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.

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).
