FrankenPHP before 1.13.4 contains a use-after-free vulnerability in worker mode that frees internal streams of SplTempFileObject or SplFileObject on php://temp instances surviving across requests. Remote clients can send requests reaching code that uses such persisted objects, causing reads of freed memory that leak garbage data or crash the process.
