      "value": "yt-dlp is a command-line audio/video downloader. Starting in version 2023.06.21 and prior to version 2026.02.21, when yt-dlp\u0027s `--netrc-cmd` command-line option (or `netrc_cmd` Python API parameter) is used, an attacker could achieve arbitrary command injection on the user\u0027s system with a maliciously crafted URL. yt-dlp maintainers assume the impact of this vulnerability to be high for anyone who uses `--netrc-cmd` in their command/configuration or `netrc_cmd` in their Python scripts. Even though the maliciously crafted URL itself will look very suspicious to many users, it would be trivial for a maliciously crafted webpage with an inconspicuous URL to covertly exploit this vulnerability via HTTP redirect. Users without `--netrc-cmd` in their arguments or `netrc_cmd` in their scripts are unaffected. No evidence has been found of this exploit being used in the wild. yt-dlp version 2026.02.21 fixes this issue by validating all netrc \"machine\" values and raising an error upon unexpected input. As a workaround, users who are unable to upgrade should avoid using the `--netrc-cmd` command-line option (or `netrc_cmd` Python API parameter), or they should at least not pass a placeholder (`{}`) in their `--netrc-cmd` argument."

A partir de la versi\u00f3n 2023.06.21 y antes de la versi\u00f3n 2026.02.21, cuando se utiliza la opci\u00f3n de l\u00ednea de comandos \u0027--netrc-cmd\u0027 de yt-dlp (o el par\u00e1metro de API de Python \u0027netrc_cmd\u0027), un atacante podr\u00eda lograr una inyecci\u00f3n de comandos arbitraria en el sistema del usuario con una URL creada maliciosamente. Los encargados del mantenimiento de yt-dlp asumen que el impacto de esta vulnerabilidad es alto para cualquiera que use \u0027--netrc-cmd\u0027 en su comando/configuraci\u00f3n o \u0027netrc_cmd\u0027 en sus scripts de Python. Aunque la URL creada maliciosamente en s\u00ed parecer\u00e1 muy sospechosa para muchos usuarios, ser\u00eda trivial explotar encubiertamente esta vulnerabilidad a trav\u00e9s de una redirecci\u00f3n HTTP para una p\u00e1gina web creada maliciosamente con una URL discreta . Los usuarios sin \u0027--netrc-cmd\u0027 en sus argumentos o \u0027netrc_cmd\u0027 en sus scripts no se ven afectados. No se ha encontrado evidencia de que este exploit se est\u00e9 utilizando. La versi\u00f3n 2026.02.21 de yt-dlp soluciona este problema validando todos los valores de \u0027machine\u0027 de netrc y generando un error ante una entrada inesperada. Como soluci\u00f3n alternativa, los usuarios que no puedan actualizarse deben evitar usar la opci\u00f3n de l\u00ednea de comandos \u0027--netrc-cmd\u0027 (o el par\u00e1metro de API de Python \u0027netrc_cmd\u0027), o al menos no deben pasar un marcador de posici\u00f3n (\u0027{}\u0027) en su argumento \u0027--netrc-cmd\u0027."
