When the validation command starts with an allowed prefix but then supplies tool options, this still returns true, so the allowlist can still be bypassed with commands such as make test -f /tmp/evil.mk. I checked GNU make's CLI (Usage: make [options] [target] ..., and -f FILE reads that makefile), and make test -f /tmp/evil.mk executes the test target from the attacker-selected file even though only make test is allowlisted. For validation configs controlled by an untrusted or compromised source, this preserves arbitrary command execution despite the intended fix.
