Description
The Live Composer – Free WordPress Website Builder plugin for WordPress is vulnerable to multiple Stored Cross-Site Scripting vulnerabilities via DOM manipulation in all versions up to, and including, 2.0.2 due to insufficient input sanitization and output escaping on user-supplied attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
