CVE-2024-5479 is a stored cross-site scripting vulnerability (CWE-79) in the Easy Pixels WordPress plugin by jevnet, affecting all versions up to and including 2.13. The issue arises from improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of plugin settings. This allows unauthenticated attackers to inject malicious scripts that execute in the context of users visiting the compromised pages. The vulnerability has a CVSS 3.1 base score of 7.2, indicating high severity with network attack vector, low attack complexity, no privileges or user interaction required, and impacts confidentiality and integrity with no availability impact.

Successful exploitation can lead to execution of arbitrary scripts in users' browsers, potentially resulting in session hijacking, defacement, or other client-side attacks. The vulnerability affects confidentiality and integrity but does not impact availability. Since the attack requires no authentication or user interaction, it poses a significant risk to sites using the vulnerable plugin versions.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling or removing the Easy Pixels plugin or restricting access to plugin settings to trusted users only. Monitor official jevnet or WordPress security channels for updates and apply patches promptly once available.
