Twelve days later CVE-2026-92804 (high) followed, for unvalidated connection configuration through 0.70.4. Both went out through NVD by VulnCheck, neither is on Nango's own advisory page, and whether Cloud was exposed is unanswered. The design around the agent is better than the record. An agent session is bound to one tenant's tagged connections, the agent never sees a raw credential and can't widen its scope, and credentials sit under AES-256-GCM with AWS KMS envelope keys. Then the gaps. No approval on writes, provider content passed straight to the agent with no injection guidance, logs kept 15 days, and the audit trail only on Enterprise.
