CVE-2026-0691

The CM E-Mail Blacklist – Simple email filtering for safer registration plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'black_email' parameter in all versions up to, and including, 1.6.2. This is due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
