Overview
openclaw is a 🦞 OpenClaw — Personal AI Assistant
Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs via the exec process when combined POSIX inline-command flags are used on macOS. An attacker can execute shell content outside the intended allowlist check by crafting command requests that leverage combined inline flags. This is only exploitable if the affected feature is enabled and reachable, and lower-trust input can access the execution path.
Workaround
This vulnerability can be mitigated by requiring approval for combined shell flag forms on macOS until patched, keeping channel and tool allowlists narrow, avoiding sharing one Gateway between mutually untrusted users, and disabling the affected feature when not needed.
