Neo ships N3 v3.10.2 patch closing multisig witness verification bypass

  • —Patch closes inconsistency between multisig script validation paths
  • —A malformed public key could pass structural checks without cryptographic decoding
  • —Two new tests added and TestIsMultiSigContract_WrongCurve updated
  • —No formal security advisory or confirmed mainnet exploitation
Why it matters: Node operators and infrastructure providers on Neo N3 should upgrade to v3.10.2 to prevent acceptance of invalid multisig transactions.
