With S = 0 and a small-order R value, an attacker who can choose the public key can produce signatures that verify for many messages, or all messages with the identity key, without a private key. This can defeat proof-of-possession, attribution, non-repudiation, or deduplication checks that rely on a signature being bound to the message. Keys produced by normal Ed25519 key generation are not small-order, so applications that verify only trusted or internally generated public keys are not affected.
