Overview
org.webjars.npm:elliptic is a Fast elliptic-curve cryptography in a plain javascript implementation.
Affected versions of this package are vulnerable to Information Exposure due to the sign function which allows an attacker to extract the private key from an ECDSA signature by signing a malformed input. A single maliciously crafted signed message can enable full key extraction for any previously known message-signature pair.
