Unauthenticated Cross Site Scripting (XSS) in Site Reviews <= 8.2.0 versions.

AnalysisAI

Cross-site scripting in the Site Reviews WordPress plugin by Gemini Labs (versions up to and including 8.2.0) allows unauthenticated attackers to inject malicious JavaScript that executes in visitors' browsers when they view affected review pages. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C) reflects that no authentication is needed to plant the payload, and the changed scope means the injected script can reach browser-origin resources beyond the plugin itself, enabling session hijacking or credential theft. …
