CVE-2026-24894 affects FrankenPHP versions prior to 1.11.2, where the $_SESSION superglobal is not properly reset between requests when running in worker mode. This allows subsequent requests to access residual session data from previous requests, potentially exposing information from other users before session_start() is called. The vulnerability is rated High severity (CVSS 7.5), with a low attack complexity and no user interaction required, potentially leading to high confidentiality impact by unauthorized access to session data. There is no integrity or availability impact. Currently, there is no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or KEV listing. Community discussion and media coverage are minimal, with only one mention and one article referencing a SUSE security update.
