Arbitrary `jku`, `x5u`, `kid` filesystem/database lookup, or token-header-selected issuers are findings. +- Key rotation caches are bounded and fail closed when the key, issuer, or metadata cannot be verified. +- Opaque access tokens are introspected or validated according to the authorization server contract instead of being parsed as JWTs. + +Findings to consider: + +| ID | Finding | +|---|---| +| OIDC-JWT-01 | Code trusts decoded JWT/OIDC claims before signature, issuer, audience, lifetime, and token-type validation. | +| OIDC-ALG-01 | Verifier accepts `none`, mixed symmetric/asymmetric algorithms, or token-selected algorithms. | +| OIDC-JWKS-01 | Verifier fetches untrusted `jku`/`x5u`, uses unsanitized `kid`, or discovers JWKS from token-controlled input. | +| OIDC-TYPE-01 | ID tokens, access tokens, refresh tokens, or session JWTs are accepted in the wrong trust context. | +| OIDC-MULTI-01 | Multi-issuer validation shares audience, algorithm, key set, or subject namespace rules across issuers. | + +### Step 4: Review Client Profile and Token Storage + +Evaluate whether the client type matches the deployed threat model. + +Required evidence: + +- Public clients do not rely on embedded client secrets for confidentiality. +- Browser-based apps use a BFF or hardened public-client pattern with PKCE, no token leakage to URLs, no access/refresh tokens in `localStorage`, and minimal exposure to third-party scripts. +- Native apps use external user agents, claimed HTTPS/app-link redirect URIs or loopback redirects, PKCE S256, and platform-protected storage. +- Refresh tokens are rotated or sender-constrained where supported, reuse is detected, and old tokens are revoked on replay, logout, or account compromise. +- Device authorization flows show clear user verification prompts, phishing-resistant wording, short code lifetime, polling limits, and no automatic account binding from user code alone. +- Logs, crash reports, analytics, browser history, referrers, and build artifacts do not retain tokens, codes, or secrets. + +Findings to consider: + +| ID | Finding | +|---|---| +| OAUTH-CLIENT-01 | Public client depends on an embedded client secret or treats it as confidential. | +| OAUTH-STORE-01 | Browser code stores access or refresh tokens in `localStorage`, persistent `sessionStorage`, URLs, logs, or analytics without compensating isolation. | +| OAUTH-REFRESH-01 | Refresh tokens lack rotation, reuse detection, revocation evidence, or sender constraints where supported. | +| OAUTH-DEVICE-01 | Device flow can be phished or bound to the wrong account because prompts, expiry, polling, or user-code handling are weak. | +| OAUTH-NATIVE-01 | Native app uses embedded webviews, custom-scheme hijackable redirects, or no PKCE for authorization code flow. | + +### Step 5: Review Resource Server Authorization + +An API that accepts OAuth tokens must prove the token was issued for that API and authorizes the requested action. + +Required evidence: + +- Resource server validates issuer and audience/resource indicator for the API, not just token signature. +- Scope/claim checks are mapped to endpoints, methods, object ownership, tenant, and business action. +- Missing, extra, or ambiguous scopes fail closed. Do not treat a valid login token as sufficient for API authorization. +- Token cache TTL is short enough to respect revocation, deprovisioning, consent withdrawal, and key rotation requirements. +- Sender-constrained tokens such as DPoP or mTLS are verified where the architecture claims replay resistance. +- Gateway validation and application authorization are consistent; one layer cannot bypass the other through alternate routes, internal hosts, or debug endpoints. + +Findings to consider: + +| ID | Finding | +|---|---| +| OAUTH-AUD-01 | API accepts tokens without the correct audience/resource binding. | +| OAUTH-SCOPE-01 | Endpoint relies on authentication only and does not enforce action/object/tenant-specific scopes or claims. | +| OAUTH-REPLAY-01 | Replay-resistance claims such as DPoP, mTLS, nonce, or proof-of-possession are not actually verified. | +| OAUTH-CACHE-01 | Token validation or introspection cache ignores revocation, deprovisioning, key rollover, or consent withdrawal windows. | + +### Step 6: Review Federation, Account Linking, and Multi-Tenant Boundaries + +Identity claims are stable only within the right issuer and tenant context. + +Required evidence: + +- Account keys use `(issuer, subject)` or another issuer-scoped immutable identifier, not email alone. +- Email-based linking requires verified email, issuer trust, collision handling, and tenant policy evidence. +- Multi-tenant apps allowlist issuers, tenant IDs, client IDs, or organizations according to business scope. +- External IdP or social-login accounts cannot silently bind to existing privileged accounts without step-up or owner approval. +- Tenant, organization, or domain claims are validated from the trusted issuer and not copied from unverified profile/userinfo data. +- Deprovisioning, consent revocation, and organization removal are reflected in session and refresh-token handling. + +Findings to consider: + +| ID | Finding | +|---|---| +| OAUTH-LINK-01 | Account linking uses email, domain, display name, or tenant claim without issuer-scoped immutable identity and verification evidence. | +| OAUTH-TENANT-01 | Multi-tenant login accepts unapproved issuers or tenants, or lets one tenant's token access another tenant's resources. | +| OAUTH-EXTIDP-01 | External/social IdP login can attach to an existing account or privileged role without step-up, approval, or verified identity proof. | + +--- + +## False Positive Calibration + +Do not report a finding solely because: + +- A JWT is decoded for diagnostics after a framework middleware has already enforced token validation and the decoded claims are not used for trust decisions. +- A public client has no client secret. Public clients are expected not to keep secrets; require PKCE, redirect binding, and storage evidence instead. +- An access token is opaque. Opaque tokens are acceptable when the resource server uses trusted introspection or gateway validation evidence. +- `SameSite=None; Secure` appears on an OIDC nonce or correlation cookie. Cross-site login flow cookies can require this setting; verify purpose and secure flag. +- A multi-tenant IdP is used. The finding is missing issuer/tenant allowlisting, subject namespacing, or audience binding, not multi-tenancy itself. + +--- + +## Output Format + +The final review output must include: + +```text +## OAuth/OIDC Security Review Report + +Scope: [applications, clients, APIs, issuers, files reviewed] +Flows reviewed: [authorization code, OIDC login, client credentials, device code, native, SPA, BFF] +Reviewer: AI Agent -
