Advisory
Source description from Wordfence Intelligence, credited to Athiwat Tiprasaharn (Jitlada).
The Qubely plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.8.14 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 an injected page.
