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

CVE-2025-54468 has a CVSS score of 4.7 (Medium). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2.12.2, 2.11.6, 2.10.10, 2.9.12); upgrading removes the vulnerable code path.

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.

1. What is CVE-2025-54468? CVE-2025-54468 is a medium-severity security vulnerability in github.com/rancher/rancher (go), affecting versions >= 2.12.0, < 2.12.2. It is fixed in 2.12.2, 2.11.6, 2.10.10, 2.9.12.
2. How severe is CVE-2025-54468? CVE-2025-54468 has a CVSS score of 4.7 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of github.com/rancher/rancher are affected by CVE-2025-54468? github.com/rancher/rancher (go) versions >= 2.12.0, < 2.12.2 is affected.
4. Is there a fix for CVE-2025-54468? Yes. CVE-2025-54468 is fixed in 2.12.2, 2.11.6, 2.10.10, 2.9.12. Upgrade to this version or later.
5. Is CVE-2025-54468 exploitable, and should I be worried? Whether CVE-2025-54468 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2025-54468 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2025-54468?
   • Upgrade github.com/rancher/rancher to 2.12.2 or later
   • Upgrade github.com/rancher/rancher to 2.11.6 or later
   • Upgrade github.com/rancher/rancher to 2.10.10 or later
   • Upgrade github.com/rancher/rancher to 2.9.12 or later
