CVE-2024-7606 is a stored cross-site scripting vulnerability in the Front End Users WordPress plugin by rustaurius, affecting all versions up to 3.2.28. The vulnerability is due to improper neutralization of input in the 'user-search' shortcode, allowing authenticated users with contributor or higher privileges to inject arbitrary JavaScript code that executes in other users' browsers. This occurs because of insufficient input sanitization and output escaping of user-supplied attributes. The CVSS 3.1 base score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, and partial confidentiality and integrity impact with no availability impact.

An attacker with contributor-level or higher access can inject persistent malicious scripts via the 'user-search' shortcode. These scripts execute in the context of other users viewing the affected pages, potentially leading to session hijacking, unauthorized actions, or data exposure limited to the confidentiality and integrity impact described. There is no impact on system availability. No known exploits have been reported 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 'user-search' shortcode if feasible to reduce exposure. Monitor vendor channels for updates and apply patches promptly once available.
