Executive Summary

CVE-2026-123012 is a vulnerability in Gogs 0.14.3 where the Git Smart HTTP authorization layer incorrectly allows write operations when only read access was intended. This happens due to case-sensitive inconsistencies in verb checks during authorization.

Impact Analysis

An attacker could push unauthorized changes to a repository they only have read access to, potentially overwriting the main branch or introducing malicious code. This affects repository integrity and availability.

Mitigation Strategies

Upgrade Gogs to a version beyond 0.14.3 to address the authorization bypass in Git Smart HTTP handling. Review repository permissions to ensure collaborators have only the intended access levels. Monitor for unauthorized pushes or modifications to repositories.
