Description

Summary Sandboxed agents could escape exec routing via host=node override. Affected Packages / Versions • Package: `openclaw` • Ecosystem: npm • Affected versions: `>= 2026.4.5 = 2026.4.10` Impact A sandboxed agent could request `host: "node"` and route exec to a remote node instead of the intended sandbox execution path, bypassing the sandbox routing boundary. Technical Details The fix blocks sandboxed exec escape to remote node targets and keeps routing aligned with the active sandbox policy. Fix The issue was fixed in #63880. The first stable tag containing the fix is `v2026.4.10`, and `[email protected]` includes the fix. Fix Commit(s) • `dffad08529202edbf34e4808788e1182fe10f6a9` • PR: #63880 Release Process Note Users should upgrade to `openclaw` 2026.4.10 or newer. The latest npm release, `2026.4.14`, already includes the fix. Credits Thanks to @zsxsoft, with sponsorship from @KeenSecurityLab and @qclawer for reporting this issue.
