CVE-2026-41929— Vvveb < 1.0.8.2 Unauthenticated Reflected XSS via Visual Editor

Vvveb < 1.0.8.2 Unauthenticated Reflected XSS via Visual Editor

Vvveb before 1.0.8.2 contains an unauthenticated reflected cross-site scripting vulnerability in the visual editor preview renderer that allows attackers to execute arbitrary JavaScript by manipulating the r query parameter and _component_ajax POST parameter. Attackers can craft a malicious link or auto-submitted form that causes victims to execute attacker-controlled JavaScript in the context of the Vvveb origin, as the gating function isEditor() performs no session, role, or token verification and the view handler injects raw HTML POST body content without sanitization.
