      "value": "PlaywrightCapture is a simple replacement for splash using playwright. Prior to 1.39.6, PlaywrightCapture did not sufficiently restrict navigations and resource requests initiated by rendered pages. An attacker-controlled page could abuse browser-side redirection mechanisms, such as window.location.href, to make the capture process open file:// URLs or request resources hosted on private, loopback, link-local, or otherwise non-public IP addresses. In deployments where PlaywrightCapture processes untrusted URLs, this could allow a remote attacker to perform server-side request forgery against internal services or attempt to access local files from the capture environment. Depending on what capture artifacts are generated and exposed, responses from those resources could potentially be leaked through screenshots, saved page content, logs, or other capture outputs. This vulnerability is fixed in 1.39.6."

      "value": "PlaywrightCapture es un reemplazo simple para splash usando playwright. Antes de la versión 1.39.6, PlaywrightCapture no restringía suficientemente las navegaciones y las peticiones de recursos iniciadas por las páginas renderizadas. Una página controlada por un atacante podría abusar de los mecanismos de redirección del lado del navegador, como window.location.href, para hacer que el proceso de captura abriera URLs de tipo file: // o solicitara recursos alojados en direcciones IP privadas, de bucle invertido, de enlace local o de otro modo no públicas. En implementaciones donde PlaywrightCapture procesa URLs no confiables, esto podría permitir a un atacante remoto realizar una falsificación de petición del lado del servidor contra servicios internos o intentar acceder a archivos locales desde el entorno de captura. Dependiendo de qué artefactos de captura se generen y expongan, las respuestas de esos recursos podrían potencialmente filtrarse a través de capturas de pantalla, contenido de página guardado, registros u otras salidas de captura. Esta vulnerabilidad se corrige en la versión 1.39.6."
