CVE-2026-67322
Description
A flaw was found in GitPython. A remote attacker can exploit a vulnerability in the Repo.clone_from() method by providing a specially crafted Git repository URL. This URL can contain references to environment variables, which are then expanded and included in the URL. This allows the attacker to exfiltrate sensitive environment variables, such as access keys or tokens, to an attacker-controlled server during the cloning process, leading to information disclosure.
Statement
This Important vulnerability in GitPython allows for sensitive environment variable exfiltration. When an application utilizes GitPython's Repo.clone_from() method with an attacker-controlled Git repository URL, embedded environment variable tokens within the URL are expanded and transmitted to a remote server. This poses a risk of information disclosure, particularly for credentials or tokens, in Red Hat products that process untrusted clone URLs.
Mitigation
To mitigate this issue, ensure that applications using GitPython's Repo.clone_from() method to clone from untrusted sources operate within a process environment that does not contain sensitive information as environment variables. Alternatively, implement strict validation and sanitization of all Git repository URLs before they are passed to Repo.clone_from() to prevent the inclusion of environment variable tokens. If the application is a service, a restart may be required for environment variable changes to take effect.
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).
