CVE-2026-123012 · Severity: info · Published 2026-11-05

Gogs is a lightweight Git service that hosts repositories. An authorization flaw in the Git Smart HTTP interface allows users with read-only access to push changes to repositories they should not be able to modify. This occurs due to inconsistent case-sensitive checking of Git operations, enabling privilege escalation within the repository access model.

## Technical details

The Git Smart HTTP authorization layer in internal/route/repo/http.go fails to consistently apply case-sensitive checks when validating whether a Git verb (push or pull operation) is authorized. An attacker with read-only access can craft a request that bypasses the authorization check and perform a push operation. The vulnerability requires network access and valid (read) credentials to the affected repository.

## Affected products

- Gogs Gogs 0.14.3
