Stored Cross-Site Scripting in the Quill Forms WordPress plugin (all versions through 5.7.1) enables unauthenticated attackers to permanently inject arbitrary JavaScript into pages rendered by the plugin. The CVSS vector (PR:N, S:C) confirms no authentication is needed to plant the payload, and the scope change indicates injected scripts execute in victims' browser sessions - enabling session hijacking, credential theft, or admin account takeover when privileged users view affected pages. Reported by Wordfence and corroborated by Patchstack; no public exploit code or CISA KEV listing has been identified at time of analysis.
