How to fix?

Upgrade to version 1.1.0 or higher.

Overview is a Package that aims to provide an implementation of the Javascript Object Signing and Encryption set of standards.

Affected versions of this package are vulnerable to Signature Validation Bypass. The go-jose library supports messages with multiple signatures. However, when validating a signed message the API did not indicate which signature was valid, which could potentially lead to confusion. For example, users of the library might mistakenly read protected header values from an attached signature that was different from the one originally validated.
