Advisory

Source description from Wordfence Intelligence, credited to Philippe Dourassov.

The Simple Ajax Chat plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 20220115 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. However, the attack requires specific conditions, making it hard to exploit.
