CVE-2025-11733 is a stored cross-site scripting vulnerability in the Footnotes Made Easy plugin for WordPress, affecting all versions up to and including 3.0.7. The vulnerability arises from improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of plugin settings. This allows unauthenticated attackers to inject arbitrary web scripts that execute in the context of users visiting the compromised pages. The vulnerability has a CVSS 3.1 score of 7.2, reflecting high severity with network attack vector, no privileges or user interaction required, and impacts confidentiality and integrity with a scope change.

Successful exploitation can lead to arbitrary script execution in the context of users visiting affected pages, potentially resulting in theft of user credentials, session hijacking, or other malicious actions impacting confidentiality and integrity. The vulnerability does not affect availability. The attack can be performed remotely without authentication or user interaction, increasing the risk.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling the Footnotes Made Easy plugin or restricting access to plugin settings to trusted administrators only.
