CVE-2022-44310Public exploitNetwork attack vector

Shared-secret exposure via unchecked elliptic-curve points

Published Feb 24, 2023 · Updated Mar 12, 2025

Invalid-curve handling in Development IL ecdh before 0.2.0 allows remote attackers to obtain a predictable derived shared secret. PrivateKey.prototype.deriveSharedSecret checks only that a public-key object and Q value exist, then multiplies the supplied point without verifying that its coordinates lie on the configured elliptic curve. An unauthenticated peer that supplies the public key can force an all-zero secret with the point (0,0), exposing confidentiality without reported integrity or availability impact.
