The Rate Star Review Vote – AJAX Reviews, Votes, Star Ratings WordPress plugin suffers from a stored cross-site scripting vulnerability (CWE-79) in its 'videowhisper_reviews' shortcode. This vulnerability arises from improper neutralization of input during web page generation, specifically due to insufficient input sanitization and output escaping of user-supplied attributes. Authenticated attackers with contributor-level privileges or higher can exploit this to inject arbitrary JavaScript code that executes in the context of users visiting the injected pages. The vulnerability affects all plugin versions up to 1.6.3. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, and impacts on confidentiality and integrity with scope change.

Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages rendered by the plugin. This can lead to unauthorized actions performed in the context of other users, potentially compromising confidentiality and integrity of user data. There is no impact on availability. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the vulnerable plugin to prevent exploitation.
