CVE-2026-118676 Details
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.
A vulnerability allowing authorization bypass has been identified in n8n versions prior to 1.123.85, 2.43.5, and 2.44.1. This vulnerability allows member users to access credentials they should not be able to by omitting default node parameters. As a result, attackers can create and execute workflows that bypass credential checks, leading to the unauthorized transmission of decrypted credential values to destinations of their choice.
Users are advised to upgrade to n8n versions 1.123.85, 2.43.5, or 2.44.1. If an immediate upgrade is not possible, consider restricting access to trusted users, auditing credential ownership, and monitoring execution logs for unexpected credential usage by member accounts.
