Vulnerability Advisory : OpenClaw < 2026.4.22 - Symlink Swap Race Condition in OpenShell FS Bridge Writes with HIGH Attack Complexity

OpenClaw before 2026.4.22 contains a time-of-check/time-of-use race condition in OpenShell sandbox filesystem writes that allows attackers to redirect writes outside the intended mount root. Attackers can exploit symlink swaps during filesystem operations to bypass sandbox restrictions and write files outside the local mount root.
