From 7ee289e2e74cd8316c73758f983f40eaf62691da Mon Sep 17 00:00:00 2001 From: Justin Bowen Date: Mon, 13 Jul 2026 20:09:15 -0500 Subject: [PATCH 01/21] fix(auth): require JWT_SECRET_KEY in prod + run config validation at startup Fixes two critical findings: - C1: JWT_SECRET_KEY no longer falls back to the dev SECRET_KEY default in production. ProductionConfig now requires it via env var and validate() rejects the dev default, closing an admin-token forgery vector. - C2: create_app() now calls ProductionConfig.validate() at startup (guarded by hasattr so Dev/Testing configs are unaffected), so the dead secret-guard actually runs and the app boot-fails on default/missing secrets.

Adds PKCE (S256) + nonce to authorize/callback. - OC2: auto-link/auto-provision gated on email_verified (+ OIDC_AUTO_LINK_ VERIFIED_EMAIL flag, default off); no more silent email-based account linking. - OH4: access/refresh tokens returned as httpOnly Secure SameSite cookies, not in the redirect URL query string. - OH5: identity linking only via authenticated OIDC round-trip; removed body-supplied external_sub/external_email linking. Adds nullable columns oidc_providers.issuer, user_oidc_links.email_verified. _encrypt_secret fail-open and update_provider gating deferred to A5.

(Also restores object-scoped authz that had regressed when team_id_param was dropped from the decorators.) - Adds _is_team_admin / _is_tenant_admin helpers (global admin scope OR team/tenant- scoped admin role for THAT object). - update/delete/add-member/remove-member on both teams.py and tenants.py now require the caller to be an admin of that specific team/tenant (or global admin). - add_team_member/add_tenant_member especially: they grant roles incl. *_admin, so non-admins of the object are now blocked. - Regression tests: global maintainer (no admin role) → 403 on every write route; team/tenant admin → 200/201. Full suite: 423 passed, 90.10% coverage.

Dev keeps the convenience default with a prominent warning. Suite: 467 passed, 90.44% coverage.

Short-code generation via secrets (not random); DB UNIQUE + bounded retry. - app/urlvalidation.py: scheme allowlist (blocks javascript:/data:/file:), rejects literal + resolved private/loopback/link-local/reserved/multicast/metadata IPs (IPv4 incl. decimal/hex/octal, IPv6); unresolvable public hostnames allowed (the server 301-redirects, never fetches).

From e380e0593cd8a0f40cf3936087f3ba16b6ddc3b5 Mon Sep 17 00:00:00 2001 From: Justin Bowen Date: Mon, 13 Jul 2026 22:46:11 -0500 Subject: [PATCH 08/21] feat(shortener): public redirect + async click tracking + QR + analytics (B3-B4) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - app/redirect.py: public GET / → 302 to long_url (404 for unknown/ inactive/expired), destination re-validated before redirect. Click tracking is non-blocking (asyncio.create_task after the response); click_count incremented atomically. link_clicks stores ip_hash (salted SHA256, never raw IP) + UA-parsed device/browser/os + referer. - QR: GET /api/v1/urls//qr (auth + urls:read + tenant-scoped) returns on-demand PNG of the short URL (qrcode+Pillow), not stored. TODO(tiering) branded/color QR. - app/analytics.py: /analytics/urls/ (per-link: total, clicks-by-day, top referers) and /analytics/summary (tenant-wide totals, top links, time series), analytics:read + tenant-scoped. Basic tiers implemented; geo/device/browser breakdowns marked TODO(tiering) for the Enterprise advanced-analytics gate. - deps: qrcode, Pillow, user-agents (pinned+hashed via uv). Tests: 619 passed, 90.66% coverage — redirect/404/expiry, async click + ip_hash, QR png, analytics date-filter/pagination/tenant-isolation.

From 524976e20f58ac867f0161194635ce085affe084 Mon Sep 17 00:00:00 2001 From: Justin Bowen Date: Mon, 13 Jul 2026 23:16:05 -0500 Subject: [PATCH 09/21] feat(shortener): Free/Pro/Enterprise tier gating via feature flags + license (B5) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two-layer gating (PostHog flag defaulted OFF + license tier), per house tier matrix: - app/features.py: feature_enabled() (graceful degradation, cached last-known, new flags OFF, never crash), get_license_tier() (free/professional/enterprise; dev & bypass-domain → enterprise; production fails CLOSED to free on error), require_tier/require_professional/require_enterprise decorators → 402 when below. - Free 5-collection cap enforced server-side in collections.py (402 on 6th; Pro/Ent unlimited) — flag current.collections. - Branded QR (color/logo params) gated to Professional in urls.py QR endpoint (plain QR stays Free) — flag current.branded-qr. - Advanced analytics (geo/device/browser/OS breakdowns) at /analytics/urls//advanced gated to Enterprise; basic analytics stays all-tiers — flag current.advanced-analytics. - config: POSTHOG_KEY/POSTHOG_HOST (default https://license.penguintech.io). Tests: 649 passed, 90% coverage; features.py 100% (tier resolution, flag degradation, each gate 402/allow, mocked posthog+license clients, no network).

Created SQLAlchemy ORM models in app/db_schema.py mirroring all 18 PyDAL tables. Generated baseline migration creating auth, RBAC, session, OIDC, and URL shortener tables. All migrations support PostgreSQL, MySQL, and SQLite. Verified upgrade/downgrade on sqlite with schema validation tests. Added comprehensive Alembic docs.

Generate a Migration + +Alembic compares the ORM models against the current database and autogenerates a migration script: + +```bash +alembic revision --autogenerate -m "Add new_column to urls table" +``` + +This creates a new file in `migrations/versions/` named like `abc123_add_new_column_to_urls_table.py`. + +### 3. Review the Migration + +Always inspect the generated migration file to ensure it's correct: + +```bash +cat migrations/versions/abc123_add_new_column_to_urls_table.py +``` + +The migration should contain: +- `upgrade()` function with correct schema changes +- `downgrade()` function to reverse changes +- Correct down_revision (points to the previous migration) + +### 4. Apply the Migration + +**Local development** (SQLite): +```bash +DB_TYPE=sqlite DB_PATH=app.db alembic upgrade head +``` + +**PostgreSQL/MySQL**: +```bash +DB_TYPE=postgresql DB_HOST=localhost DB_NAME=app_db alembic upgrade head +``` + +**Production** (Kubernetes Job only — see deployment guide): +```bash +# Never automatic; always manual via K8s Job before app deployment +alembic upgrade head +``` + +### 5.

All redis-dependent paths have fallback logic. Production deployment: Provide GEOIP_DB_PATH to enable geo lookups; if absent, gracefully continues with country/region/city = None.

DNS-rebinding/TOCTOU: validate_destination_url() checked DNS resolution, but httpx re-resolved during fetch, allowing attacker to return public IP during validation then private IP during connection. Fixed by resolving hostname ONCE via socket.getaddrinfo and pinning httpx connection to validated IP. 2. Redirect bypass: httpx.follow_redirects=True bypassed validation on 3xx targets. Fixed by manually validating each redirect Location header before following (max 3 hops). Any redirect to private/reserved IP is blocked. Implementation: - _get_first_public_ip(): Resolve hostname to IP once, return first public IP - _fetch_with_redirect_validation(): Manual redirect handling with re-validation for each hop, connections pinned to pre-resolved IP via URL replacement - Supports relative redirects (resolved against current URL) - Returns final response without following invalid redirects Tests added: - test_ssrf_dns_rebinding_attack: Validates TOCTOU is prevented - test_ssrf_redirect_to_private_blocked: Validates redirect validation - test_ssrf_redirect_with_valid_target: Validates valid redirects follow - test_ssrf_max_redirect_limit: Validates redirect loop prevention - test_ssrf_relative_redirect: Validates relative redirect resolution Coverage: 90.22% (729 tests passing) Co-Authored-By: Claude Fable 5 --- services/flask-backend/app/link_previews.py | 234 ++++++++++---- .../flask-backend/tests/test_link_previews.py | 285 +++++++++++++++--- 2 files changed, 431 insertions(+), 88 deletions(-) diff --git a/services/flask-backend/app/link_previews.py b/services/flask-backend/app/link_previews.py index 8bdbffce..9d5b1ed8 100644 --- a/services/flask-backend/app/link_previews.py +++ b/services/flask-backend/app/link_previews.py @@ -2,7 +2,7 @@ Link previews with OpenGraph/meta tag parsing and server-side fetch.

Also verify every candidate IP is public in _get_first_public_ip so a rebinding second resolution to a private/metadata IP is rejected rather than pinned.
