This omission weakens browser-level defenses and exposes users to cross-site scripting (XSS), clickjacking, and referer leakage. Although some instances attempt to enforce CSP via HTML <meta> tags, this method is ineffective, as modern browsers rely on header-based enforcement to reliably block inline scripts and untrusted resources."}, {"lang": "es", "value": "Existe una vulnerabilidad de configuraci\u00f3n incorrecta de seguridad del lado del cliente en la plataforma de denuncia OpenBlow en m\u00faltiples versiones e implementaciones predeterminadas, debido a la ausencia de encabezados de respuesta HTTP cr\u00edticos, como Content-Security-Policy, Referrer-Policy, Permissions-Policy, Cross-Origin-Embedder-Policy y Cross-Origin-Resource-Policy. Esta omisi\u00f3n debilita las defensas del navegador y expone a los usuarios a ataques de cross-site scripting (xss), clickjacking y fugas de referencias. Aunque algunos casos intentan aplicar la CSP mediante etiquetas HTML , este m\u00e9todo resulta ineficaz, ya que los navegadores modernos dependen de la aplicaci\u00f3n basada en encabezados para bloquear de forma fiable los scripts en l\u00ednea y los recursos no confiables."}], "lastModified": "2025-07-29T14:14:55.157", "sourceIdentifier": "disclosure@vulncheck.com"}
