Technical details

A Stored Cross-Site Scripting (XSS) vulnerability exists in the Crocoblock JetReviews plugin for WordPress (versions 3.0.0.1 and below). The flaw stems from improper neutralization of user-supplied input during web page generation (CWE-79). An attacker with Subscriber-level authentication can inject malicious HTML or JavaScript payloads into review-related fields. The exploit requires a victim (such as an administrator) to interact with the affected page or perform a specific action for the script to execute. Successful exploitation allows for session hijacking, unauthorized administrative actions, or site defacement. The issue is resolved in version 3.0.0.2.
