phpBB contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the 'bb_memberlist.php' script not properly sanitizing user-supplied input to the 'sortby' parameter. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
