Detailed vulnerability description
The vulnerability allows a remote authenticated user to manipulate data.
mod/forum/post.php in Moodle 2.9.x before 2.9.1 does not consider the mod/forum:canposttomygroups capability before authorizing "Post a copy to all groups" actions, which allows remote authenticated users to bypass intended access restrictions by leveraging per-group authorization.
