Description
OmniAgent through commit 12b98c5 contains an approval bypass vulnerability in ReflexionAgent._is_safe_bash_command that treats any command starting with find as safe without inspecting -execdir arguments. Prompt-injected agents can run find with -execdir to invoke binaries like dd, nc, perl or openssl through an unsandboxed shell, overwriting files or executing code without human approval.
