It was reported that firejail does not respect the end-of-options separator ("--"), allowing an attacker with control over the command line options of the sandboxed application, to write data to a specified file (CVE-2020-17367).

It was reported that firejail when redirecting output via --output or --output-stderr, concatenates all command line arguments into a single string that is passed to a shell. An attacker who has control over the command line arguments of the sandboxed application could take advantage of this flaw to run arbitrary commands (CVE-2020-17368).
