 "title": "wpForo Forum <= 3.2.4 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Attachment File Name",
 "description": "The wpForo Forum plugin for WordPress is vulnerable to Stored Cross-Site Scripting via attachment file names in forum post content in all versions up to, and including, 3.2.4. This is due to the attachment file name being URL-decoded and printed without output escaping when the post is displayed to users who are not permitted to view attachments. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in forum posts that will execute whenever such a user accesses the post.",
