CVE-2025-55182: Meta React Server Components Remote Code Execution

Use AI to implement and verify

1. Inspect: Inventory every owned instance of Meta / react-server-dom-webpack, Meta / react-server-dom-turbopack, Meta / react-server-dom-parcel; record its location, owner, exact version, exposure, and the read-only evidence used to decide whether it is affected.
2. Change: Propose the smallest change that implements the bounded fallback: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. Show the exact diff or command plan and dependency impact; do not apply it yet.
3. Approval: Require the repository, service, or security owner to approve the affected asset, target version, maintenance window, backup, and mutation scope before any write.
4. Test: After approval, confirm the decoded representation contains data values only and cannot instantiate arbitrary application or library classes and save the commands and results.
5. Rollback: Define failure triggers before the change. If a trigger fires, stop the rollout and use the approved application, database, configuration, or deployment-artifact recovery procedure with a release confirmed not affected by the cited vendor evidence. Never automatically downgrade into an affected version; if no known-safe recovery target exists, isolate the asset and escalate to its owner and vendor. Preserve the failure evidence for triage.

Stop before mutation if product identity, affected range, fixed version, ownership, or approval is unresolved.
Return an inventory, source decision, proposed diff/commands, approval request, test evidence, rollback status, and unresolved assumptions.
