Prior to 4.0.0-beta.474, the HMAC key is the application&#39;s manual_webhook_secret_github field, which is used by Coolify&#39;s webhook endpoints to validate incoming requests, is nullable with no default — meaning newly created applications have a null webhook secret. PHP&#39;s hash_hmac() function silently coerces a null key to an empty string &#39;&#39;. So when the secret is null, the server computes hash_hmac(&#39;sha256&#39;, $payload, &#39;&#39;) — a deterministic value that any attacker can calculate independently. By sending X-Hub-Signature-256: sha256=&lt;hash_hmac(&#39;sha256&#39;, payload, &#39;&#39;)&gt;, an unauthenticated attacker can forge a valid signature and trigger deployments. This vulnerability is fixed in 4.0.0-beta.474.</p> <p><strong>Affected:</strong> coollabsio coolify</p> <p>Coolify is an open-source and self-hostable tool for managing servers, applications, and databases.
