CVE-2026-73620
Description
A flaw was found in GitPython. This vulnerability arises from insufficient guarding of git option forwarding within the IndexFile.checkout() and TagReference.create() functions. An authenticated attacker can exploit this by passing unsafe options through keyword arguments, leading to the ability to overwrite arbitrary files with repository content or read sensitive files. This could result in significant data integrity and confidentiality impacts.
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.
