phpBB is one of the most used forum software in the web and a critical security issue has been found.
We've been notified about a vulnerability in phpBB 2.0.6 (which also affects 2.0.5). The fix is noted below but please note the text that follows it. [...]A change was made to the way bbcode url matching is achieved around phpBB 2.0.4. This was done following complaints that our existing methods, as used in earlier releases of phpBB were too restrictive. Unfortunately the match went from too restrictive to too loose. This allows people to "break out" of the anchor href and insert arbitary markup, particularly event handling parameters. This can result in anything from "nuisance" posts to people exploiting cross-site issues to grab cookie data. Therefore this exploit is deemed serious ... we advise all our users to deploy the following fix as soon as possible. Updated 2.0.6 packages will be available shortly for new users.
