HIGH 7.5

DescriptionGitHub Advisory

FrankenPHP is a modern application server for PHP. Prior to 1.11.2, when running FrankenPHP in worker mode, the $_SESSION superglobal is not correctly reset between requests. This allows a subsequent request processed by the same worker to access the $_SESSION data of the previous request (potentially belonging to a different user) before session_start() is called. This vulnerability is fixed in 1.11.2.

AnalysisAI

FrankenPHP versions prior to 1.11.2 fail to properly isolate session data between worker requests, enabling cross-user session fixation where an attacker can read sensitive $_SESSION information intended for other users. This high-severity flaw affects multi-request worker mode deployments and has public exploit code available. A patched version 1.11.2 is available and should be deployed immediately.

Technical ContextAI

Classified as CWE-269 (Improper Privilege Management). Affects Frankenphp. FrankenPHP is a modern application server for PHP. Prior to 1.11.2, when running FrankenPHP in worker mode, the $_SESSION superglobal is not correctly reset between requests.
