Security Review detailsBest possible solution: Land the fail-closed sandbox HTTP guard only after owner review confirms the protected-target policy and upgrade impact, keeping the bridge aligned with shared OpenClaw net-policy and the Codex Do we have a high-confidence way to reproduce the issue? Yes. Current main source shows the sandbox HTTP helper accepts any HTTP(S) URL and calls Is this the best way to solve the issue? Yes, with owner approval. The best fix layer is the OpenClaw sandbox exec-server bridge because Codex forwards executor HTTP through AGENTS.md: found and applied where relevant.

RelevanceThe advisory targets a shipped production path in the Codex sandbox exec-server CompatibilityThe change is safe from a compatibility standpoint. The TypeScript import uses the existing plugin-safe SDK subpath ClawSweeperClawSweeper reviewed the initial commit and identified two P1 blockers: the Python in-sandbox SSRF classifier missed cloud metadata addresses and site-local IPv6 targets that OpenClaw net-policy explicitly blocks, and real behavior proof was missing. Both have been addressed in the current branch head — the Python classifier was extended with comprehensive coverage including cloud metadata literals, CGNAT/RFC2544 ranges, blocked IPv6 special-use ranges, and embedded IPv4 transition form detection, and real behavior proof was posted showing the patched bridge blocking protected targets while ordinary public HTTP still succeeds through the live JSON-RPC bridge. Code Reviews CompletedMultiple code reviews were completed across the full lifecycle of the PR. All reviews agreed on the architectural soundness of the two-layer defense (TypeScript preflight + Python in-sandbox guard), the correct plugin boundary usage, and the narrow scope. The policy gap identified in the first pass was fixed and confirmed clean in the final code review. Complete Verification Table
