CVE-2024-11442 is a stored Cross-Site Scripting vulnerability in the gopiplus Horizontal scroll image slideshow WordPress plugin. The issue stems from improper neutralization of input during web page generation, specifically in the 'horizontal-scroll-image-slideshow' shortcode. Authenticated users with contributor or higher privileges can inject arbitrary JavaScript code due to insufficient sanitization and escaping of shortcode attributes. This code executes in the context of users viewing the injected pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to and including 10.1. The CVSS 3.1 base score is 6.4, reflecting a network attack vector, low attack complexity, and limited privileges required.

Successful exploitation allows authenticated contributors or higher to inject persistent malicious scripts into pages using the vulnerable shortcode. These scripts execute in the browsers of users who view the affected pages, potentially compromising user sessions or performing unauthorized actions within the context of the site. The impact is limited to confidentiality and integrity loss with no availability impact reported. There are no known exploits in the wild at this time.

No official patch or remediation has been published by the vendor as of the provided data. Users should monitor the vendor's advisory channels for updates and apply patches promptly once available. Until then, restrict contributor-level access to trusted users only and consider disabling or removing the vulnerable plugin to prevent exploitation.
