CVE-2026-68766

hashcat fails to restrict command-line options when parsing restore files, allowing attackers to inject output-redirecting options like --outfile and --potfile-path. Attackers can craft restore files with malicious options to append attacker-controlled content to arbitrary files, enabling code execution when targeting shell startup files.

Summary		(es) hashcat falla al restringir las opciones de línea de comandos al analizar archivos de restauración, permitiendo a los atacantes inyectar opciones de redirección de salida como --outfile y --potfile-path. Los atacantes pueden crear archivos de restauración con opciones maliciosas para añadir contenido controlado por el atacante a archivos arbitrarios, permitiendo la ejecución de código al apuntar a archivos de inicio de shell.
