      "value": "Speakr is a personal, self-hosted web application designed for transcribing audio recordings. Prior to 0.8.20-alpha, the is_safe_url() helper used to validate post-login redirect targets applied urljoin(request.host_url, target) before parsing, while the controller passed the raw target to redirect(). A scheme-relative input such as ////evil.com resolved to a same-host URL during validation but was emitted verbatim in the Location header, where the browser interpreted it as a network-path-relative redirect to an attacker-controlled host. This vulnerability is fixed in 0.8.20-alpha."

      "value": "Speakr es una aplicación web personal, autoalojada, diseñada para transcribir grabaciones de audio. Antes de 0.8.20-alpha, la función auxiliar is_safe_url() utilizada para validar los objetivos de redirección post-inicio de sesión aplicaba urljoin(request.host_url, target) antes del análisis, mientras que el controlador pasaba el objetivo en bruto a redirect(). Una entrada relativa al esquema como ////evil.com se resolvía a una URL del mismo host durante la validación, pero se emitía textualmente en el encabezado Location, donde el navegador la interpretaba como una redirección relativa a la ruta de red a un host controlado por un atacante. Esta vulnerabilidad está corregida en 0.8.20-alpha."
