Description
The BlockArt Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the -clientId- block attribute in all versions up to, and including, 2.2.15. This is 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.
