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.
