- openclaw (npm): fixed in 2026.4.22

## Description

OpenClaw before 2026.4.22 contains a time-of-check/time-of-use race condition in the OpenShell filesystem bridge that allows attackers to read files outside the intended mount root. Attackers can exploit symlink swaps during filesystem operations to bypass sandbox restrictions and access unauthorized file contents.
