CVE-2026-60004
About
Gitea before 1.27.1 allows remote code execution via the diffpatch API through Git hook installation.
Rainforest analyst review
Gitea before 1.27.1 allows the diffpatch API to be abused to install a Git hook — a script that Git runs automatically on repository events such as receiving a push. By writing an attacker-controlled hook through that API path, an ordinary-looking repository operation is turned into arbitrary code execution on the server that hosts the repository, since the malicious hook runs with the privileges of the Gitea process the next time its triggering event fires.
Gitea is a self-hosted Git service, and while many instances are internal they are frequently exposed for developer and CI access, which puts a code-execution foothold squarely in the software supply chain: source code, stored credentials, and build pipelines all sit within reach. Upgrade to 1.27.1 or later, restrict who can reach the affected API and repository administration features, and audit repositories for unexpected server-side hooks, since a planted hook persists until someone removes it regardless of the patch.
