Vulnerability in Spring Spring Security. When an application configures JWT decoding with NimbusJwtDecoder or NimbusReactiveJwtDecoder, it must configure an OAuth2TokenValidator<Jwt> separately, for example by calling setJwtValidator. This issue affects Spring Security: from 6.3.0 through 6.3.14, from 6.4.0 through 6.4.14, from 6.5.0 through 6.5.9, from 7.0.0 through 7.0.4.
