CVE-2026-42435: OpenClaw 2026.2.22 < 2026.4.12 - Shell-Wrapper Detection Bypass via Environment Variable Assignment Injection

OpenClaw versions from 2026.2.22 before 2026.4.12 contain an insufficient shell-wrapper detection vulnerability allowing attackers to inject environment variable assignments at the argv level. Attackers can bypass exec preflight handling to manipulate high-risk shell variables like SHELLOPTS and PS4, affecting execution semantics and security controls.
