SiYuan versions before v3.7.4 disclose encrypted-notebook key-derivation material and wrapped data keys through unauthenticated endpoints in publish mode. Attackers can retrieve Argon2id salt, cost parameters, password verifiers, and wrapped notebook keys to perform unlimited offline master-password cracking without rate limiting.
