Incomplete or skipped token validation in APIs

9/10 Critical

APIs frequently validate only that a token is present rather than performing full server-side validation of signature, issuer, audience, expiry, and required scopes, leaving the system vulnerable to forged or expired tokens.

Query: “What are the most common pain points with OAuth 2.0 for developers in 2025?”3/31/2026

Another frequent pitfall is only checking that 'a token is present' without actually validating it... Your resource server should: Verify the token's signature against a trusted key set (JWKS). Check `iss` (issuer), and `aud` (audience) match what your API expects.
