CVE-2016-9121: Go-Jose Project Go-Jose

Critical severity, CVSS 9.1. EPSS: 1.4% chance of exploitation in the next 30 days.

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.

Affected products
