Description
The Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 3gp2 file uploads in all versions up to, and including, 7.5.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the 3gp2 file.
