CyberRota Analysis
AI-GeneratedInstances of n8n prior to versions 2.27.4 and 2.28.1 are vulnerable due to improper handling of JWT claims, allowing attackers to authenticate as victims by exploiting trusted token-exchange issuers. This could lead to unauthorized access to sensitive workflows and data. Organizations using n8n with multiple trusted issuers should prioritize updating to the latest versions to mitigate this risk.

Original NVD Description
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.
