Overview
Affected versions of this package are vulnerable to Use of a Broken or Risky Cryptographic Algorithm in the Presignature::set_derivation_path and Presignature::issue_partial_signature functions. An attacker can significantly reduce the cryptographic security level or forge signatures by manipulating presignatures in conjunction with HD wallet derivation or by signing hashed messages without access to the original message.
Note: This is only exploitable if presignatures are used with HD wallet derivation or for raw signing without the original message.
