Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.56%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

OpenClaw versions prior to 2026.2.22 fail to sanitize shell startup environment variables HOME and ZDOTDIR in the system.run function, allowing attackers to bypass command allowlist protections. Remote attackers can inject malicious startup files such as .bash_profile or .zshenv to achieve arbitrary code execution before allowlist-evaluated commands are executed.
