CVE-2024-11424 is a stored cross-site scripting vulnerability in the Slick Sitemap plugin for WordPress, affecting all versions up to 2.0.0. The issue stems from improper neutralization of input during web page generation, specifically in the 'slick-sitemap' shortcode, where user-supplied attributes are not properly sanitized or escaped. Authenticated attackers with contributor or higher privileges can exploit this to inject arbitrary JavaScript that executes in the context of users visiting the injected pages. This can lead to partial confidentiality and integrity impacts but does not affect availability.

The vulnerability allows authenticated users with contributor-level or higher permissions to inject malicious scripts that execute in the browsers of users viewing the compromised pages. This can lead to limited confidentiality and integrity impacts, such as session hijacking or unauthorized actions performed on behalf of users. The CVSS 3.1 base score is 6.4 (medium severity), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial impact on confidentiality and integrity without affecting availability.

No official patch or fix is currently documented for this vulnerability. Users should monitor the vendor's advisory channels for updates. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the Slick Sitemap plugin if possible to prevent exploitation.
