Phpbb : Security Vulnerabilities, CVEs, (CSRF) CVSS score >= 5

phpBB 3.2.8 allows a CSRF attack that can approve pending group memberships.

In phpBB before 3.1.7-PL1, includes/acp/acp_bbcodes.php has improper verification of a CSRF token on the BBCode page in the Administration Control Panel. An actual CSRF attack is possible if an attacker also manages to retrieve the session id of a reauthenticated administrator prior to targeting them.

phpBB version 3.2.7 allows the stealing of an Administration Control Panel session id by leveraging CSRF in the Remote Avatar feature. The CSRF Token Hijacking leads to stored XSS

The message_options function in includes/ucp/ucp_pm_options.php in phpBB before 3.0.13 does not properly validate the form key, which allows remote attackers to conduct CSRF attacks and change the full folder setting via unspecified vectors.
