CVE-2024-5218 is a stored cross-site scripting vulnerability in the designextreme Reviews and Rating – Google Reviews WordPress plugin. The flaw exists in the file upload functionality, allowing authenticated users with Author-level privileges or higher to inject arbitrary web scripts due to inadequate input sanitization and output escaping. These scripts execute when any user accesses the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to and including 5.2. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, and limited privileges required.

An attacker with Author-level access or higher can exploit this vulnerability to inject malicious scripts that execute in the context of users viewing the affected pages. This can lead to information disclosure or session hijacking. The impact is limited to confidentiality and integrity, with no availability impact reported. No known exploits in the wild have been documented.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Author-level access to trusted users only and consider disabling or limiting the plugin's file upload feature.
