Summary
matrix-appservice-irc is a Node.js IRC bridge for Matrix. Prior to version 1.0.1, it is possible to craft a command with newlines which would not be properly parsed. This would mean you could pass a string of commands as a channel name, which would then be run by the IRC bridge bot. Versions 1.0.1 and above are patched. There are no robust workarounds to the bug. One may disable dynamic channels in the config to disable the most common execution method but others may exist.

"value": "matrix-appservice-irc es un puente IRC Node.js para Matrix. Antes de la versi\u00f3n 1.0.1, era posible crear un comando con nuevas l\u00edneas que no se analizaba correctamente. Esto significaba que pod\u00edas pasar una cadena de comandos como nombre de canal, que luego ser\u00eda ejecutado por el bot del puente IRC. Las versiones 1.0.1 y superiores est\u00e1n parcheadas. No hay soluciones robustas para el fallo. Uno puede desactivar los canales din\u00e1micos en la configuraci\u00f3n para desactivar el m\u00e9todo de ejecuci\u00f3n m\u00e1s com\u00fan, pero pueden existir otros.\n"
