n8n Workflow Automation Multiple Vulnerabilities

Authenticated users in n8n versions prior to 1.123.23 and 2.6.4 can bypass external secrets permission checks to retrieve plaintext secret values from configured vaults by referencing secrets by name in credentials, even without list permissions. This allows unauthorized access to sensitive vault-stored credentials without requiring admin or owner privileges, provided the attacker knows or can guess the target secret name. Public exploit code exists for this vulnerability.

n8n contains an LDAP injection vulnerability in the LDAP node's filter escape logic that allows LDAP metacharacters to pass through unescaped when user-controlled input is interpolated into LDAP search filters. This affects n8n versions prior to 1.123.27, 2.13.3, and 2.14.1, enabling attackers to manipulate LDAP queries to retrieve unintended directory records or bypass authentication controls implemented within workflows. The vulnerability requires specific workflow configuration (LDAP node receiving external user input via expressions) and has not been publicly reported as actively exploited, though no proof-of-concept availability is explicitly confirmed across available intelligence sources.
