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.
