Description
picoclaw <=v0.1.2 and earlier is vulnerable to OS command injection via the ExecTool component (pkg/tools/shell.go). The guardCommand() function attempts to restrict shell command execution using a denylist of 8 regular expressions, but the denylist is incomplete.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/sipeed/picoclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of github.com/sipeed/picoclaw has shipped for GHSA-cv2p-68f4-f4pw yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
