Harden
CertificateUtilsSPIFFE ID extraction by filtering Subject Alternative Name entries to URI SANs before casting SAN values, and wrap SPIFFE ID parse failures inCertificateException.Why
Non-URI SAN values can use non-string value types, which could previously cause
ClassCastExceptionbefore the SAN type was checked. Malformed SPIFFE URI SANs could also let unchecked parsing exceptions escape trust validation paths.How tested
Ran:
./gradlew :java-spiffe-core:test --tests io.spiffe.internal.CertificateUtilsTest
