Headline
GHSA-qw22-8w9r-864h: io.micronaut.security:micronaut-security-oauth2 has invalid IdTokenClaimsValidator logic on aud
Summary
IdTokenClaimsValidator skips aud claim validation if token is issued by same identity issuer/provider.
Details
See https://github.com/micronaut-projects/micronaut-security/blob/master/security-oauth2/src/main/java/io/micronaut/security/oauth2/client/IdTokenClaimsValidator.java#L202
This logic violates point 3 of https://openid.net/specs/openid-connect-core-1_0.html#IDTokenValidation.
Workaround exists by setting micronaut.security.token.jwt.claims-validators.audience with valid values.
micronaut.security.token.jwt.claims-validators.openid-idtoken can be kept as default on.
PoC
Should probably be:
return issuer.equalsIgnoreCase(iss) &&
audiences.contains(clientId) &&
validateAzp(claims, clientId, audiences);
Impact
Any OIDC setup using Micronaut where multiple OIDC applications exists for the same issuer but token auth are not meant to be shared.
