      "value": "changedetection.io is a free open source web page change detection tool. Prior to 0.54.7, the `jq:` and `jqraw:` include filter expressions allow use of the jq `env` builtin, which reads all process environment variables and stores them as the watch snapshot. An authenticated user (or unauthenticated user when no password is set, the default) can leak sensitive environment variables including `SALTED_PASS`, `PLAYWRIGHT_DRIVER_URL`, `HTTP_PROXY`, and any secrets passed as env vars to the container. Version 0.54.7 patches the issue."

      "value": "changedetection.io es una herramienta gratuita de código abierto para detección de cambios en páginas web. Antes de la versión 0.54.7, las expresiones de filtro de inclusión ’jq:’ y ’jqraw:’ permiten el uso de la función incorporada ’env’ de jq, que lee todas las variables de entorno del proceso y las almacena como la instantánea de vigilancia. Un usuario autenticado (o un usuario no autenticado cuando no se establece una contraseña, que es el valor predeterminado) puede filtrar variables de entorno sensibles, incluyendo ’SALTED_PASS’, ’PLAYWRIGHT_DRIVER_URL’, ’HTTP_PROXY’, y cualquier secreto pasado como variables de entorno al contenedor. La versión 0.54.7 corrige el problema."
