OpenClaw 2026.2.23 < 2026.4.12 - Weakened Exec Approval Binding via busybox and toybox Applet Execution

Assigner: VulnCheck
Reserved: 01.05.2026 Published: 05.05.2026 Updated: 05.05.2026

OpenClaw versions 2026.2.23 before 2026.4.12 contain a weakened exec approval binding vulnerability in busybox and toybox applet execution that allows attackers to obscure which applet would actually run. Attackers can exploit opaque multi-call binaries to bypass exec approval mechanisms and weaken risk classification of unsafe applet invocations.
