Title

Nango < 0.71.6 Missing Authentication RCE via runner tRPC server

Summary

Nango before 0.71.6 contains a missing authentication vulnerability in the runner tRPC server that allows unauthenticated attackers to execute arbitrary JavaScript code by invoking the exposed start procedure without credentials. Attackers with network access to the runner port can send requests to the unauthenticated start procedure, bypassing the unenforced RUNNER_SECRET_KEY environment variable, to achieve remote code execution within the runner process.

Severity
