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

CoolLabs Coolify 授权问题漏洞
Vulnerability Description
coolLabs Coolify是coolLabs团队开源的一个开源和自托管的 Heroku/Netlify/Vercel 替代品。 CoolLabs Coolify 4.0.0-beta.474之前版本存在授权问题漏洞,该漏洞源于HMAC密钥可为空且默认值为null,导致PHP的hash_hmac()函数将空键强制转换为空字符串,使得攻击者可计算哈希值并伪造签名触发部署。
