Unauthenticated Cross Site Scripting (XSS) in Business Directory <= 6.4.22 versions.

AnalysisAI

Unauthenticated cross-site scripting in the Business Directory WordPress plugin (versions <= 6.4.22) allows remote attackers without any authentication to inject and store arbitrary JavaScript that executes in the context of a victim's browser when they visit an affected page. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C) confirms network-accessible exploitation requiring no privileges, with a scope change indicating the payload crosses from the plugin's execution context into the victim's browser session. …
