Severity ?
8.4 (High) - CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Summary
A client-side security misconfiguration vulnerability exists in OpenBlow whistleblowing platform across multiple versions and default deployments, due to the absence of critical HTTP response headers including Content-Security-Policy, Referrer-Policy, Permissions-Policy, Cross-Origin-Embedder-Policy, and Cross-Origin-Resource-Policy. 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.

      "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."
