Out of 181 teams participating in the competition, only 8 managed to solve this task. And in doing so, they did the AsmBB project a huge favor.
Several XSS vulnerabilities and one serious RCE were disclosed.
So, I recommend everyone to upgrade to the latest version of trunk.
I'll wait a week or so to see if any new bug reports appear and plan to issue an official v2.10 release.
P.S. Unfortunately I am still too busy with a RL projects, but I hope to find some free time in the coming months to work more actively on this and other free projects.
