CVE-2026-126385

n8n before 2.45.5, 2.46.x before 2.46.1, and 3.x before 3.0.1 contains a flaw in the OAuth2 credential callback of the dynamic-credential connect flow, which does not verify that the completing browser belongs to the user who started the flow. Members with access to a resolvable OAuth2 credential can send the provider authorization URL to a victim; if the victim consents without an active n8n session, the victim's tokens are stored under the member's identity, letting the member's workflows act as the victim.

Part of the AI stack

This affects n8n, in Agent frameworks.
