Researcher Luigi Gubello

Description

The Page Builder: KingComposer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via an unknown parameter in versions up to, and including, 2.8.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers able to access the post editor to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
