    Insufficient Verification of Data Authenticity

    Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity in public key functions public_key_from_numbers, EllipticCurvePublicNumbers.public_key, load_der_public_key, and load_pem_public_key, which may reveal bits from a private key when provided with a malicious public key as input. When the application is using sect* binary curves for verification - which is a rare use case - these functions do not verify that the provided point belongs to the expected prime-order subgroup of the curve. An attacker can thus expose partial private keys or forge signatures.

    How to fix Insufficient Verification of Data Authenticity?

    Upgrade cryptography to version 46.0.5 or higher.
