BIP-322 address ownership verification bypass for P2WPKH and P2SH-P2WPKH addresses

Affected versions of bip322 accepted a BIP-322 proof created with an attacker-controlled private key as a valid signature for an unrelated victim P2WPKH or P2SH-P2WPKH address, allowing complete authentication bypass in applications using verifysimple, verifysimpleencoded, verifyfull, or...

Improper Verification of Cryptographic Signature

Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to improper enforcement of the SIGHASH value in the signature verification process. An attacker can submit non-compliant signatures that are incorrectly accepted as valid by providing...
