CVE-2019-16993

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

CVE-2019-13776

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

For Debian 8 'Jessie', these problems have been fixed in version 3.0.12-5+deb8u4.

We recommend that you upgrade your phpbb3 packages.
