Description

This security bulletin contains information about 1 vulnerability.


1) Improper input validation (CVE-ID: CVE-2026-34986)

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper input validation in JWE decryption in key_wrap.go when processing a JWE object with a key wrapping algorithm and an empty encrypted_key field. A remote attacker can send a specially crafted JWE object to cause a denial of service.

The issue is reachable through ParseEncrypted(), ParseEncryptedJSON(), or ParseEncryptedCompact() followed by Decrypt(), and applications are affected only if accepted key algorithms include key wrapping algorithms.
