cryptography: cryptography Subgroup Attack Due to Missing Subgroup Validation for SECT Curves

A validation flaw has been discovered in the python cryptography package. This missing validation allows an attacker to provide a public key point P from a small-order subgroup. This can lead to security issues in various situations, such as the most commonly used signature verification ECDSA and...

CVE-2026-26007

CVE-2026-26007 describes a vulnerability in the cryptography package where public_key_from_numbers, EllipticCurvePublicNumbers.public_key(), load_der_public_key(), and load_pem_public_key() do not validate that a key point belongs to the expected prime-order subgroup. This allows small-subgroup k...
