Frequently Asked Questions
Who can exploit this issue?
An attacker must be authenticated and able to supply connection configuration values that are interpolated into provider token or proxy URL templates.
What systems or data could be exposed?
The vulnerable server can be induced to make requests to internal network addresses or cloud metadata endpoints. This may allow exfiltration of provider credentials.
Are default deployments affected?
The available information does not establish whether the affected URL templates are present or reachable in a default configuration. Exposure depends on whether caller-supplied connection configuration is interpolated into provider token or proxy URL templates.
How can I determine whether my deployment is affected?
Check whether the Nango version is 0.70.4 or earlier and whether authenticated users can control connection configuration values used in provider token or proxy URL templates.
