      "value": "Kakoune is a code editor. Prior to version 2026.05.21, the bundled, enabled by default, `autorestore.kak` script can be exploited by malicious backup files leading to arbitrary kakoune and shell commands being executed by simply opening a file. Kakoune 2026.05.21 fixes the issue. As a workaround, add `autorestore-disable` to the user kakrc will disable the autorestore feature."

Antes de la versión 2026.05.21, el script ’autorestore.kak’ incluido y habilitado por defecto puede ser explotado por archivos de copia de seguridad maliciosos, lo que lleva a la ejecución de comandos arbitrarios de kakoune y de shell simplemente abriendo un archivo. Kakoune 2026.05.21 corrige el problema. Como solución alternativa, añadir ’autorestore-disable’ al kakrc del usuario deshabilitará la función de autorestore."
