Medium (6.5) in objectcomputing micronaut security. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in io.micronaut.security:micronaut-security-oauth2 3.1.2, 3.10.2, 3.11.1.
Micronaut Security is a security solution for applications. Prior to versions 3.1.2, 3.2.4, 3.3.2, 3.4.3, 3.5.3, 3.6.6, 3.7.4, 3.8.4, 3.9.6, 3.10.2, and 3.11.1, IdTokenClaimsValidator skips `aud` claim validation if token is issued by same identity issuer/provider. Any OIDC setup using Micronaut where multiple OIDC applications exists for the same issuer but token auth are not meant to be shared. This issue has been patched in versions 3.1.2, 3.2.4, 3.3.2, 3.4.3, 3.5.3, 3.6.6, 3.7.4, 3.8.4, 3.9.6, 3.10.2, and 3.11.1.
