Description
OpenClaw's system.run shell-wrapper detection did not recognize PowerShell -EncodedCommand forms as inline-command wrappers.
In allowlist mode, a caller with access to system.run could invoke pwsh or powershell using -EncodedCommand, -enc, or -e, and the request would fall back to plain argv analysis instead of the normal shell-wrapper approval path. This could allow a PowerShell inline payload to execute without the approval step that equivalent -Command invocations would require.
Latest published npm version: 2026.3.2
Fixed on main on March 7, 2026 in 1d1757b16f48f1a93cd16ab0ad7e2c3c63ce727d by recognizing PowerShell encoded-command aliases during shell-wrapper parsing, so allowlist mode continues to require approval for those payloads. Normal approved PowerShell wrapper flows continue to work.
