Description

This PR upgrades the indirect dependency github.com/go-jose/go-jose/v4 from v4.1.3 to v4.1.4 to patch CVE-2026-34986, a high-severity denial of service vulnerability.
The vulnerability causes a panic during JWE (JSON Web Encryption) decryption when: - The alg field specifies certain key wrapping algorithms (ending in KW, except A128GCMKW, A192GCMKW, A256GCMKW)

• The encrypted_key field is empty This triggers an invalid slice allocation in cipher.KeyUnwrap(), causing the application to panic.
