Description

OpenClaw's complex interpreter pipelines could skip exec script preflight validation

Summary

Before OpenClaw 2026.4.2, exec script preflight validation could fail open on complex interpreter invocations such as pipes or other non-simple command forms. In those cases, script-content validation could be skipped entirely.

Impact

An attacker-controlled command shape could bypass the intended preflight validation for script execution. This weakened a defense-in-depth guard that was meant to block unsafe script content before execution.
