What
Reject empty expected audience sets in JWT-SVID validation for both
JwtSvid.parseAndValidate(...)andJwtSvid.parseInsecure(...).Why
Passing an empty expected audience set previously caused audience validation to succeed because
containsAll(emptySet())is always true. This was a failure-open behavior in a security-sensitive validator.This is an observable behavior change: empty expected audiences now throw
IllegalArgumentException("audience cannot be empty").How tested
Ran the focused JWT-SVID validation tests:
./gradlew :java-spiffe-core:test --tests 'io.spiffe.svid.jwtsvid.JwtSvidParseAndValidateTest' --tests 'io.spiffe.svid.jwtsvid.JwtSvidParseInsecureTest'
