CVE-2026-67323
Description
A flaw was found in GitPython where it fails to properly sanitize dangerous Git options. This vulnerability allows an attacker to inject arbitrary commands when using functions like Repo.archive() and git.ls_remote(), potentially leading to arbitrary code execution. Additionally, functions such as Repo.iter_commits() and Repo.blame() do not validate revision arguments, which could allow an attacker to truncate arbitrary files. Exploitation requires an application to pass attacker-controlled input directly to these vulnerable methods.
Statement
This is an Important vulnerability because it allows for arbitrary code execution or file truncation. The flaw in GitPython requires an application to process attacker-controlled input through specific GitPython methods, such as Repo.archive() or git.ls_remote(), to be exploited. This could lead to a compromise of confidentiality, integrity, and availability on affected Red Hat products that utilize GitPython in such a manner.
Mitigation
To mitigate the risk, ensure that applications utilizing GitPython are run within a sandboxed environment with minimal privileges. This limits the potential impact of arbitrary command execution or file truncation if an attacker successfully exploits the vulnerability through an application processing untrusted input. Review applications that interact with GitPython to ensure all input is properly sanitized and validated before being passed to methods such as Repo.archive(), git.ls_remote(), Repo.iter_commits(), or Repo.blame().
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).
