Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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.
