NVD description

A vulnerability in the Cisco node-jose open source library before 0.11.0 could allow an unauthenticated, remote attacker to re-sign tokens using a key that is embedded within the token. The vulnerability is due to node-jose following the JSON Web Signature (JWS) standard for JSON Web Tokens (JWTs). This standard specifies that a JSON Web Key (JWK) representing a public key can be embedded within the header of a JWS. This public key is then trusted for verification. An attacker could exploit this by forging valid JWS objects by removing the original signature, adding a new public key to the header, and then signing the object using the (attacker-owned) private key associated with the public key embedded in that JWS header.

General
7/8 — kid / jku abuse If the output token has a different kid than the input, dig in. Issuers that resolve signing keys from kid/jku/x5u headers may fetch attacker-controlled JWKS. End state: you sign your own admin tokens. CVE-2018-0114 class bugs still ship in 2026.
Post summary
The post highlights that JWT issuers accepting kid/jku/x5u headers can fetch attacker‑controlled JWKS, allowing forged admin tokens, and notes that CVE‑2018‑0114 class bugs continue to appear in 2026.
