"Critical issue" isn't really enough to go on here. Are we talking arbitrary PHP code execution or something lesser like SQL injection or slipping HTML into the bbCode? Neither the phpBB Changelog or any advisories seem to mention what the scope of this is. I'm guessing it's arbitrary PHP code execution based on what previous vulnerabilities in phpBB have yielded, but it would be nice to know for sure. Rich.
