Unauthenticated cross-site scripting in the Facebook for WooCommerce WordPress plugin version 3.7.5 and earlier allows remote attackers to inject and execute arbitrary JavaScript in a victim's browser without any prior authentication. The scope change (S:C) in the CVSS vector confirms the script executes in the victim's browser context, enabling session hijacking, credential theft, or malicious redirects against WooCommerce store visitors or administrators. No public exploit code has been identified at time of analysis, and this vulnerability has not been added to the CISA KEV catalog.
Cross-site scripting in the Facebook for WordPress plugin (versions up to and including 5.2.1) allows unauthenticated remote attackers to inject and execute arbitrary JavaScript in a victim's browser by delivering a crafted URL or page. The CVSS vector confirms no authentication is required (PR:N) and that the attack crosses into the victim's browser security context (S:C), enabling session hijacking, credential harvesting, or page defacement against any user who interacts with the malicious content.
