CVE-2024-5965 is a stored cross-site scripting vulnerability in the wildweblab Mosaic WordPress theme affecting all versions up to 1.7.1. The issue is due to improper neutralization of input in the 'link' parameter of the Button shortcode, allowing authenticated users with Contributor-level privileges or higher to inject arbitrary web scripts. These scripts execute when any user accesses the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS 3.1 score of 6.4, reflecting a medium severity with network attack vector, low attack complexity, and no user interaction required.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable 'link' parameter. These scripts execute in the context of users viewing the affected pages, potentially compromising user sessions or performing unauthorized actions. The impact is limited to confidentiality and integrity with no direct availability impact. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Contributor-level access to trusted users only and consider disabling or removing the vulnerable Button shortcode if feasible. Monitor official wildweblab or WordPress security channels for updates and apply patches promptly once available.
