What is CVE-2025-11885?

The EchBay Admin Security plugin for WordPress suffers from a reflected cross-site scripting vulnerability via the '_ebnonce' parameter, affecting all versions up to and including 1.3.0. Insufficient input sanitization and inadequate output escaping make it feasible for unauthenticated attackers to inject malicious web scripts. This could enable attackers to trick users into executing harmful actions, such as clicking on compromised links, which may put the security of the WordPress sites at risk.
