------------------------------------------------
> camel-oauth: honor the JWT nbf (not before) claim when authenticating bearer
> tokens with the servlet backend
> ------------------------------------------------------------------------------------------------------------
>
> Key: CAMEL-25022
> URL: https://issues.apache.org/jira/browse/CAMEL-25022
> Project: Camel
> Issue Type: Improvement
> Components: camel-oauth
> Reporter: Andrea Cosentino
> Assignee: Andrea Cosentino
> Priority: Major
> Fix For: 4.23.0
>
>
> When {{OAuthBearerTokenProcessor}} authenticates an access token through the
> Jakarta servlet backend ({{ServletOAuth}}), {{UserProfile}} validates the JWS
> signature and the issuer, and {{UserProfile.expired()}} evaluates the {{exp}}
> claim. The {{nbf}} (not before) claim is copied into the profile attributes
> but is never evaluated. RFC 7519 section 4.1.5 specifies that a JWT must not
> be accepted for processing before its {{nbf}} time.
> The other token validation paths of the module already evaluate {{nbf}}: the
> Vert.x backend ({{VertxOAuth}}, through Vert.x {{User.expired(leeway)}}) and
> the {{OAuthTokenValidationFactory}} SPI ({{JwtTokenValidator}}).
> Proposed change:
> * In {{UserProfile}}, reject a token whose {{nbf}} is later than the current
> time plus the leeway configured in {{JWTOptions}} ({{getLeeway()}}, default
> 0, the same default as the Vert.x backend and the SPI {{clock-skew-seconds}}
> option).
> * Add unit tests for a token with a future {{nbf}}, a past {{nbf}}, and an
> {{nbf}} within the leeway.
