0 A vulnerability in Bouncy Castle for Java before version 1.86 affects the opt-in key-size validation for CMS key-transport recipients when using RFC 9709 content-encryption key derivation (id-alg-cek-hkdf-sha256). The validation logic incorrectly compares incompatible data types, causing the key-size check to be skipped. This allows acceptance of EnvelopedData or AuthEnvelopedData messages with mismatched key sizes despite validation being enabled. The issue also impacts Bouncy Castle for Java FIPS before versions 2.0.13 and 2.1.13. Non-HKDF messages and recipients without validation enabled are unaffected.
