Vulnerability in WP Customer Area — CVE-2026-116551

What to do now

Update WP Customer Area to 8.4.1 or later.

Affected versions

• Everything up to and including 8.4.0

The WP Customer Area plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'display_name' parameter in all versions up to, and including, 8.4.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
