CVE-2021-45886

An issue was discovered in PONTON X/P Messenger before 3.11.2. Anti-CSRF tokens are globally valid, making the web application vulnerable to a weakened version of CSRF, where an arbitrary token of a low-privileged user (such as operator) can be used to confirm actions of higher-privileged ones (such as xpadmin).
