Published Aug 20, 2025 · Updated Apr 28, 2026

Reflected XSS in LambertGroup HTML5 Radio Player - WPBakery Page Builder Addon 2.5 and earlier allows remote attackers to execute script. Patchstack identifies reflected XSS but does not disclose the affected parameter, code locus, or input-handling operation that reflects the payload. A victim must follow a crafted request; the injected script then runs in the victim's browser context and can read or alter data accessible to that session.
