CVE-2026-59208 · n8n: Cross-Issuer Token Exchange Account Binding via Subject-Only Identity Resolution
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
n8n is an open source workflow automation platform. Prior to 2.27.4 and from 2.28.0 prior to 2.28.1, n8n instances configured with more than one trusted token-exchange issuer resolved external identities to local accounts using only the JWT sub claim and ignored the iss claim, allowing an attacker with a valid token from one trusted issuer and a sub matching a victim under another issuer to authenticate as that victim. This issue is fixed in versions 2.27.4 and 2.28.1.
