Dokploy: Arbitrary File Write + Remote OS Command Injection via `certificatePath`

Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, the apiCreateCertificate schema in packages/server/src/db/schema/certificate.ts accepts a client-supplied certificatePath, and packages/server/src/services/certificate.ts joins that value to the certificate root without confinement. An authenticated user with certificate create or delete permission can use certificatePath to write attacker-controlled certificate content outside the intended directory or delete an out-of-root directory. This vulnerability is fixed in 0.29.13.
