Vulnerability from github – Published: 2025-09-26 13:02 – Updated: 2025-10-23 20:13

Summary

Rancher sends sensitive information to external services through the `/meta/proxy` endpoint

Details

Impact

A vulnerability has been identified within Rancher Manager whereby Impersonate-Extra-* headers are being sent to an external entity, for example amazonaws.com, via the /meta/proxy Rancher endpoint. These headers may contain identifiable and/or sensitive information e.g. email addresses.

If the authentication provider is configured to have email or other sensitive and/or identifiable information as part of the username and principal ID then when a new cloud credential is being created in Rancher Manager this information is sent to an external entity such as amazonaws.com, in case of an AWS cloud credentials, in Impersonate-Extra-Username and/or Impersonate-Extra-Principalid headers. Please note that neither password, password hashes or Rancher’s related authentication tokens are leaked in those requests.

The entities to which such information is sent to are limited by the whitelisted domains specified in nodedrivers.management.cattle.io objects.

For example, the Amazon EC2 node driver contains the following whitelisted domains:

iam.amazonaws.com
iam.us-gov.amazonaws.com
iam.%.amazonaws.com.cn
iam.global.api.aws
ec2.%.amazonaws.com
ec2.%.amazonaws.com.cn
ec2.%.api.aws
eks.%.amazonaws.com
eks.%.amazonaws.com.cn
eks.%.api.aws
kms.%.amazonaws.com
kms.%.amazonaws.com.cn
kms.%.api.aws

While the DigitalOcean driver contains the following whitelisted domain:

api.digitalocean.com

Patches

This vulnerability is addressed by filtering all Impersonate-* headers from the original request by the /meta/proxy endpoint.

Patched versions of Rancher include releases v2.12.2, v2.11.6, v2.10.10, and v2.9.12.

Workarounds

There are no known workarounds for this issue.
