What is CVE-2016-9122?

The go-jose library, prior to version 1.0.4, is susceptible to multiple signatures exploitation due to improper handling of signature validation. Users might be misled about which signature from a signed message is valid, as the API does not clearly indicate the validated signature. This flaw could result in users unintentionally leveraging protected header values from non-original signatures, leading to potential security risks within applications utilizing the library.
