"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.
