Summary by CodeRabbit

• New Features
  • Configure managed proxy DNS records through Cloudflare when setup is available, then return to Swetrix to verify the domain. Manual DNS setup remains available.
  • Edit IP allowlists and blocklists using tag-style inputs that support adding, changing, and removing entries.
• Documentation
  • Added guidance for Cloudflare setup and verification, including configuration requirements and manual DNS alternatives.

📝 Walkthrough

Walkthrough

Adds an opt-in Cloudflare Domain Connect flow for managed proxy DNS setup, including signed setup URLs, project-settings initiation, and return verification. Replaces the IP blacklist and whitelist text fields with tag-based inputs that autosave changes.

Changes

Cloudflare Domain Connect Setup

Layer / File(s)	Summary
Domain Connect signing and configuration backend/.env.example, backend/domain-connect/*, backend/apps/cloud/src/project/proxy-domain-connect.*, backend/jest.proxy.config.js	Adds signing configuration and a managed-proxy template. The service validates configuration and generates signed setup URLs. Tests cover signing and validation cases; the README documents setup and verification.
Project-domain setup endpoint backend/apps/cloud/src/project/project.module.ts, backend/apps/cloud/src/project/proxy-domain.controller.ts, backend/apps/cloud/src/project/proxy-domain-connect-controller.spec.ts	Registers the service and adds an authenticated endpoint that checks project access, looks up a domain, and returns its setup URL. The domain-list response reports whether setup is available.
Project settings setup and return flow web/app/routes/projects.settings.$id.tsx, web/app/pages/Project/Settings/components/ProxyDomainsTab.tsx, docs/content/docs/adblockers/managed-proxy.mdx, web/public/locales/en.json	Adds route actions to report setup availability and request a setup URL. The settings tab redirects to the URL and handles return parameters by showing an error or submitting verification for a matching domain. Adds setup instructions and messages.

IP List Editing

Layer / File(s)	Summary
Tag input behavior web/app/ui/TagInput.tsx	Adds a controlled tag input that parses delimited values and supports editing, removal, keyboard input, paste, and error feedback.
IP-list settings integration web/app/pages/Project/Settings/tabs/Shields.tsx, web/app/pages/Project/Settings/ProjectSettings.tsx, web/public/locales/en.json	Uses the tag input for blacklist and whitelist fields. Changes autosave through field-specific handlers, and the UI displays editing instructions.

Merge Risk: 🟡 Moderate · up to 02e8d

IP-list edits can leave saved settings different from the displayed list, and a failed domain-list request can prevent automatic verification after Cloudflare setup. Fix the autosave reversal and preserve pending Cloudflare returns before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 02e8d

DNS setup is protected by project-management checks and restricted signing configuration. However, rapid IP-list edits can leave a protection exception saved after it disappears from the editor, and the external DNS approval and signed-link lifecycle remain unverified.

Retained concerns

• Medium · security · inferred: The new immediate tag-editing workflow can persist an IP-policy change that the editor shows as undone. Starting with an empty saved whitelist, adding an address submits a save; removing it while that save is active matches lastSavedForm and is discarded before entering the pending queue. Successful completion advances the saved baseline without restoring the visible form. The retained address bypasses the project's bot-detection chain. The queue defect predates this PR, but immediate tag commits are new; equivalent exposure through the previous editor remains incompletely compared.

Security review details

Security Blast Radius

• inferred — The demonstrated policy-state divergence affects the edited project's analytics filtering. A matching IP can retain a bot-detection exemption, but the inspected path does not establish cross-project access or administrative privilege gain. Locally issued DNS setup URLs are bound to project-selected stored domains and a fixed managed-proxy target pattern; actual provider-side exposure remains unverified.

Security Findings and Attack Paths

• inferred — An authorized manager can add a whitelist address and remove it before the addition finishes saving. The removal can be discarded while the address remains persisted and invisible in the editor. Traffic matching that address then bypasses bot detection despite the apparent retraction. This requires a manager's policy-editing sequence; no unauthenticated policy-write path was established. The head behavior is source-supported, while its incremental exposure over the prior editor remains partially unresolved.

Trust Boundaries and Controls

• observed — DNS URL issuance requires authentication and management authority held by the project administrator, a confirmed admin share, or a confirmed organization administrator/owner. Domain lookup includes project ID and domain ID, and request data does not directly supply the signed hostname or target.
• observed — The signer requires an HTTPS client origin, an RSA key of at least 2048 bits, the expected managed-proxy base domain, and a hexadecimal target identifier. It signs the encoded query with RSA-SHA256. Documentation specifies separate Cloudflare user approval; local signing alone does not prove provider enforcement, and the generated query contains no visible expiry or ownership version.

Resilience and Maintainability Implications

• observed — Cloudflare return parameters are only verification triggers, not activation authority. Missing DNS or TLS evidence prevents LIVE status, and the verifier can recover on later checks. A failed initial list can consume the return trigger without verification, but it displays a list-error notification; this does not establish insecure domain activation.

Hardening Proposals

• proposed — Preserve the latest desired IP-policy value across active and pending saves, including reversals to the old saved baseline. Reconcile completion with that desired state so an acknowledged save cannot silently leave an obsolete bot exemption authoritative.
• proposed — Before enabling the integration, establish provider-side signature, template, redirect, and zone-consent behavior using the documented onboarding checks. Define the intended lifetime of issued links and behavior after domain deletion or ownership changes, including responsibility for external DNS cleanup; missing local expiry alone is not evidence of unauthorized DNS access.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Queue reversals while an autosave is in flight.

The new IP-list handler submits each committed change immediately. Start with an empty list, add an IP address, then remove it before the request completes. The removal matches lastSavedForm, so this early return discards it. The first request then saves the IP address, while the UI shows an empty list.

Compare the update with the effective pending or in-flight value. Queue a compensating update when the user restores the saved value during an active request.
