CVE-2022-24895

28
FAUCET Score

CVE-2022-24895 is a high-severity vulnerability affecting Symfony, a PHP framework, that allows same-site attackers to bypass CSRF protection. This occurs because Symfony regenerates the session ID but retains CSRF tokens upon user login, enabling a session-fixation-like attack. The vulnerability carries a CVSS score of 8.8 (HIGH), indicating a network-based attack with low complexity that can lead to high impact on confidentiality, integrity, and availability. There is currently no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
