Auth0 security checklist: 22 na item

Na Auth0 dua na identity-as-a-service platform kei na surface levu โ€” applications, APIs (resource servers), tenants, actions, rules (legacy), connections, kei na grants. Na misconfiguration ni dua e dua na auth bypass. Na checklist oqo na 22-item audit ena applications, callback / logout allowlists, tokens kei na refresh rotation, custom actions, RBAC, anomaly detection, kei na ongoing monitoring. Na item yadua e rawa ni verify ena Auth0 Dashboard ena loma ni 10 na minisi.

Me equivalent checklist ena Clerk, vakaraica Clerk security checklist. Me rai ki na vuna na identity-layer misconfigurations era AI-tool blind spots, vakaraica Na vuna na AI coding tools era biuta tu na security gaps.

Application type kei na grant types

Na application type kei na enabled grant types era settings ena impact levu duadua ena Auth0. Na nodra cala e dolava na classes ni attack ka sega ni dua na frontend code e rawa ni sogo.

  1. Vakayagataka na Application Type = Single Page Application me browser-only apps kei na Regular Web Application me server-rendered apps. Na type cala e vakadonuya na grant types cala โ€” e.g., e dua na Regular Web App kei na SPA grant e enable na PKCE-less Implicit flow, e leak na tokens mai na URL fragments.
  2. Disable na Implicit grant type ena application yadua. Dashboard โ†’ Application โ†’ Advanced Settings โ†’ Grant Types โ†’ uncheck Implicit. Na Implicit flow e tukuna mai na tokens ena URL fragments, era logged ena browser history kei na analytics. Vakayagataka na Authorization Code kei na PKCE.
  3. Disable na Password grant ke sega ni dua na documented need. Na Resource Owner Password Credentials (ROPC) grant e vinakata mo qarauna na user passwords vakataki iko โ€” ka defeat na levu na ka o voli kina na Auth0. Disable ke sega ni integrate kei na legacy system.
  4. Enable Authorization Code kei na PKCE ena public client yadua. Dashboard โ†’ Advanced Settings โ†’ OAuth โ†’ JsonWebToken Signature Algorithm = RS256, OIDC Conformant = enabled. Na PKCE e gadrevi me mobile apps kei na SPAs me vakatabuya na code interception.

Callback kei na logout URL allowlists

Na open redirects ena OAuth callback path na token-theft primitive. Na Auth0 allowlist na nomu duabau na vakacegu.

  1. Biuta na Allowed Callback URLs ki na nomu exact production callback path โ€” sega na wildcards. https://yourapp.com/callback, sega https://yourapp.com/*. Na wildcard callbacks era vakadonuya na attackers me redirect na tokens ki na arbitrary subpaths ena nomu domain.
  2. Biuta na Allowed Logout URLs ki na finite list. Rule vata: explicit URLs ga. E dua na open logout redirect e vakadonuya na attackers me craft phishing pages era vaka na nomu post-logout state.
  3. Biuta na Allowed Web Origins ki na nomu production origin ga. Vakayagataki me silent authentication (token renewal mai na hidden iframe). E dua na wildcard origin e vakadonuya na attacker pages me cakava na silent auth ki na nomu tenant.
  4. Biuta na Allowed CORS origins ena API endpoints, sega na application. Tenant Settings โ†’ Advanced โ†’ Allowed CORS origins. Na default lala (restricted); kuria ga na explicit origins o iko e qarauna.

Tokens kei na refresh rotation

Na token lifetime, refresh rotation, kei na signing algorithm era lewa na blast radius ni dua na token leak.

  1. Enable na Refresh Token Rotation. Application โ†’ Refresh Token Settings โ†’ Rotation. Na refresh yadua e issue e dua na refresh token vou ka invalidate na makawa. Vakatautaki kei na absolute expiry, oqo e qarauna na token theft.
  2. Biuta na Refresh Token Reuse Interval ki na 0 (se lailai vakacava na nomu replay tolerance). Na reuse interval e vakadonuya na token me vakayagataki ena 2 na gauna ena window vata โ€” biuta me off ke sega ni dua na vuna mo maroroya.
  3. Biuta na Absolute Refresh Token Expiry ki na 14-30 na siga, sega na sega ni mudu. Application โ†’ Refresh Token Expiration โ†’ Absolute Expiration. Na Auth0 e default ki na Inactivity-only, kena ibalebale na idle session e tudei ena vica na yabaki.
  4. Biuta na JWT Signature Algorithm ki na RS256. Application โ†’ Advanced โ†’ OAuth โ†’ JsonWebToken Signature Algorithm. Na RS256 e vakayagataka na asymmetric signing o koya na client e sega ni rawa ni forge na tokens. Kakua sara ni vakayagataka na HS256 me client-facing applications.
  5. Verify na aud kei na iss claims ena JWT yadua e taura na nomu API. Vakayagataka na official Auth0 SDK ena server side โ€” e verify na ka oqo vakaautomatiki. Na hand-rolled JWT parsing e dau biu na audience validation, e dua na auth bypass.

Actions kei na custom code

Na Auth0 Actions (kei na legacy Rules) era cici ena server-side ena login kei na tale na lifecycle events. Era kei na access ki na request context taucoko. Na insecure code ena vanua oqo e dua na tenant-wide vulnerability.

  1. Kakua sara ni log na event.user se event.transaction me whole object. Era vakacurumi na email addresses, IP addresses, kei na tale na PII. Vakayagataka na field-level logging ga, ka log ga na ka o vinakata.
  2. Vakayagataka na secrets store me API key se webhook URL. Actions โ†’ Edit โ†’ Secrets. Kakua sara ni inline e dua na API key me string literal ena action code โ€” na code e raitaki ki na ka kece kei na Action editor access ena tenant.
  3. Validate na inputs ni bera ni persist me user_metadata se app_metadata. E dua na self-service action e vola event.body.name ki user.user_metadata.display_name e dua na stored-XSS vector ke render na nomu frontend na field oqo sega ni escaping.

RBAC kei na resource servers

Ke o vakayagataka na Auth0 RBAC, na role-to-permission mapping na nomu authorization layer. Na nona cala kei na authenticated user kece e rawa ni hit na admin endpoints.

  1. Define na Resource Servers (APIs) matata ena Auth0 Dashboard, sega na ena gauna sara. Na API yadua kei na identifier (na audience), scopes, kei na signing settings. Kevaka sega ni dua na registered API, na tokens kece era issued me implicit "Auth0 Management API" โ€” audience cala.
  2. Configure na Permissions ena API yadua ka vinakata ena nomu code kei na scope claim. Kakua ni check na role membership ena nomu application logic; check na scopes ena access token. Na scopes na OAuth-native authorization mechanism.
  3. Test ni e dua na authenticated user sega na required role / scope e sega ni rawa ni hit na privileged endpoints. Sign in vaka normal user, tovolea me call POST /api/admin/users/delete. Na response me 403.

Anomaly detection kei na tenant logs

Na Auth0 e emit na high-signal events. Set me alert na nomu team, sega ga ni tu ena log buffer.

  1. Enable Attack Protection: Bot Detection, Brute Force, Suspicious IP Throttling. Dashboard โ†’ Security โ†’ Attack Protection. Na yadua e off ena free tiers; vakacurumi kece ena production.
  2. Stream na tenant logs ki na SIEM se na nomu application logs. Dashboard โ†’ Monitoring โ†’ Streams. Na Auth0 e retain na logs me 30 na siga ena levu na plans; me long-term retention me vakaitavi e dua na stream ki na nomu system.
  3. Alert ena fcoa (failed cross-origin auth) kei na fp (failed login) spikes. Na burst ena window lekaleka na credential stuffing. Route ki na nomu on-call channel.

Tikitiki tarava

Cakava e dua na FixVibe scan ki na nomu production URL โ€” na baas.clerk-auth0 check e flag na Auth0 client secrets bundled ena JavaScript kei na tale na identity-provider exposure classes. Me equivalent ena Clerk, vakaraica Clerk security checklist. Me rai vakatauvatani ena BaaS providers, wilika BaaS misconfiguration scanner.

// scan na nomu baas surface

Kune na teveli sa dola ni bera ni kunea e dua tale.

Vakacurumi mai e dua na production URL. Sa wilika na FixVibe na BaaS provider e veivosaki kaya na nomu app, sa fingerprint na nodra public endpoints, ka tukuna na ka e rawa ni wilika se vola e dua na unauthenticated client. E sega ni saumi, sega ni install, sega ni card.

  • Free tier โ€” 3 scan / vula, sega ni gadrevi na card ena signup.
  • Passive BaaS fingerprinting โ€” sega ni gadrevi me veivakadinadinataki na domain.
