## Summary Before OpenClaw 2026.4.2, the OpenShell mirror backend accepted arbitrary absolute `remoteWorkspaceDir` and `remoteAgentWorkspaceDir` values. In mirror mode, those paths were then used as the target of remote cleanup and overwrite operations. ## Impact If an attacker could influence those OpenShell config values, mirror sync could delete the contents of an unintended remote directory and replace them with uploaded workspace data. This was a destructive remote-path bug in the mirror-sync path. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `<= 2026.4.1` - Patched versions: `>= 2026.4.2` - Latest published npm version: `2026.4.1` ## Fix Commit(s) - `b21c9840c2e38f4bb338d031511b479d5f07ca25` — constrain OpenShell mirror sync roots ## Release Process Note The fix is present on `main` and is staged for OpenClaw `2026.4.2`. Publish this advisory after the `2026.4.2` npm release is live. Thanks @jufeng123768 for reporting.
