CVE-2026-43530Network attack vector

Authenticated command execution via opaque applet dispatch

Published May 5, 2026 · Updated May 5, 2026

Incorrect authorization in OpenClaw before 2026.4.12 allows remote authenticated users to bypass exec approval for unsafe applets. The run-plan logic in src/node-host/invoke-system-run-plan.ts treated busybox and toybox as ordinary safe executables, binding approval to the multiplexer name instead of the dispatched applet or script behavior. Exposure begins with 2026.2.23 and requires low-privileged network access plus an exec path that can invoke either multi-call binary; successful abuse executes commands outside the intended approval decision.
