LowCVSS 3.7/10Last modified Nov 13, 2026

Description

FrankenPHP before 1.13.4 contains a double free vulnerability in worker mode that frees SG(request_info).content_type_dup twice when a worker script ends its loop after a non-form POST request. Unauthenticated attackers can send repeated JSON POST requests until the worker loop ends, aborting the whole process when USE_ZEND_ALLOC=0 is set.
