Description
n8n before 1.123.85, 2.43.5, and 2.44.1 contains an authorization bypass vulnerability that allows member users to use credentials they cannot access by omitting default node parameters. Attackers can save and run workflows where pre-execution checks skip credential slots, causing decrypted credential values to be sent to attacker-chosen destinations.
