hi:
I find a vulnerability in version 6.8.3-stable, an attacker can exploit this vulnerability to delete or read any files on the server,it can also be used to determine whether a file exists.
In b2evolution/inc/files/files.ctrl.php,the parameter 'fm_selected[]' is vulnerable. So an attacker can use ../../../../ to traversal directory.
If you want to know more details about the vulnerability, please send me an email.My email is blackwolf5240@gmail.com
