Name of the Vulnerable Software and Affected Versions OpenClaw versions 2026.2.22 through 2026.4.11
Description Insufficient shell-wrapper detection allows attackers to inject environment variable assignments at the argv level. This enables the bypass of exec preflight handling to manipulate high-risk shell variables, such as SHELLOPTS and PS4, which can affect execution semantics and security controls.
Recommendations Update to version 2026.4.12 or newer.
