Description
n8n before 2.46.1 contains a credential exposure vulnerability that forwards Authorization headers and basic auth credentials on cross-origin redirects because sendCredentialsOnCrossOriginRedirect defaults to true. Attackers controlling a redirect target or an expression-fed URL in credential-using nodes can capture stored workflow credentials sent to their endpoint.
