CVE-2016-9121
Elliptic curve key disclosure in github.com/square/go-jose
9.1
CRITICAL
CVSS 3.1
EPSS 0.19%
Description
go-jose before 1.0.4 suffers from an invalid curve attack for the ECDH-ES algorithm. When deriving a shared key using ECDH-ES for an encrypted message, go-jose neglected to check that the received public key on a message is on the same curve as the static private key of the receiver, thus making it vulnerable to an invalid curve attack.
