    Improper Verification of Cryptographic Signature

    sjcl is a Stanford Javascript Crypto Library

    Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to missing point-on-curve validation in sjcl.ecc.basicKey.publicKey(). An attacker can recover a victim's ECDH private key by sending crafted off-curve public keys and observing ECDH outputs. The dhJavaEc() function directly returns the raw x-coordinate of the scalar multiplication result (no hashing), providing a plaintext oracle without requiring any decryption feedback.

    How to fix Improper Verification of Cryptographic Signature?

    Upgrade sjcl to version 1.0.9 or higher.
