Kerentanan Generation of Error Message Containing Sensitive Information pada n8n. Skor CVSS 3.1 6.5 (Medium) menurut NVD.

Deskripsi (NVD)

n8n versions before 1.123.69, 2.33.4, and 2.34.1 contain an information disclosure vulnerability in the GraphQL node. When a GraphQL request fails at the connection level, the node re-throws the underlying HTTP client error unchanged instead of wrapping it in n8n's standard error type. That error contains the live request's headers, including a decrypted credential secret, which the execution engine persists verbatim. Any authenticated user able to read the resulting execution can retrieve the decrypted credential secret from the stored run data.
