Summary

Go JOSE Panics in JWE decryption in github.com/go-jose/go-jose

Description

The go-jose package is subject to a panic when decrypting certain JSON Web Encryption (JWE) tokens. This occurs when an attacker can provide a maliciously crafted JWE token that triggers an unhandled exception during the decryption process, leading to a denial-of-service.
