CVE-2026-25934

Description

A flaw was found in go-git, a library for Git implementation in Go. This vulnerability allows a remote attacker to provide specially crafted Git pack or index files that are not properly verified for data integrity. Successful exploitation could lead to the go-git library processing corrupted data, which may result in unexpected application errors such as 'object not found'.

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).
