GHSA-f434-223j-r8rm PUBLISHED CVSS 9.300000190734863 CRITICAL

Record from GitHub Advisory Database · Published May 1, 2022

Double free vulnerability in the session extension in PHP 5.2.0 and 5.2.1 allows context-dependent attackers to execute arbitrary code via illegal characters in a session identifier, which is rejected by an internal session storage module, which calls the session identifier generator with an improper environment, leading to code execution when the generator is interrupted, as demonstrated by triggering a memory limit violation or certain PHP errors.
