In 7z even using -- before * (note that -- means that the following input cannot treated as parameters, so just file paths in this case) you can cause an arbitrary error to read a file, so if a command like the following one is being executed by root:
And you can create files in the folder were this is being executed, you could create the file @root.txt and the file root.txt being a symlink to the file you want to read:
Then, when 7z is execute, it will treat root.txt as a file containing the list of files it should compress (thats what the existence of @root.txt indicates) and when it 7z read root.txt it will read /file/you/want/to/read and as the content of this file isn't a list of files, it will throw and error showing the content.
