Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate this vulnerability, European organizations using affected Rancher versions should: 1) Immediately review and restrict the use of the `/meta/proxy` endpoint to trusted internal destinations only, ensuring that no sensitive headers are forwarded to external or untrusted domains. 2) Implement strict network egress filtering to prevent unauthorized outbound connections from Rancher Manager to external cloud domains unless explicitly required and verified. 3) Audit and sanitize HTTP headers, particularly `Impersonate-Extra-*` headers, to ensure they do not contain sensitive information before forwarding or proxying requests. 4) Monitor Rancher logs and network traffic for unusual or unexpected outbound requests containing sensitive headers. 5) Educate users and administrators about the risk of user interaction-based exploitation and enforce least privilege principles to minimize exposure. 6) Stay alert for official patches or updates from SUSE and apply them promptly once available. 7) Consider deploying Web Application Firewalls (WAFs) or API gateways that can detect and block suspicious header forwarding or proxy misuse. 8) Review and update incident response plans to include scenarios involving sensitive data exposure through management platforms like Rancher.

Description

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.

Impact

For European organizations, the exposure of sensitive user information such as email addresses can have several adverse effects. Firstly, it can lead to privacy breaches violating GDPR regulations, potentially resulting in legal penalties and reputational damage. Secondly, leaked information can be used by threat actors to craft targeted phishing campaigns or social engineering attacks, increasing the risk of credential compromise or lateral movement within networks. Since Rancher is commonly used in cloud-native environments and DevOps pipelines, attackers gaining reconnaissance information can better tailor attacks against critical infrastructure or intellectual property. Although the vulnerability does not directly allow system compromise or denial of service, the confidentiality loss can be a stepping stone for more severe attacks. The fact that the headers are sent to external domains like amazonaws.com raises concerns about data exfiltration to third-party cloud services, which may be outside the control of the affected organization. This is particularly sensitive for organizations handling regulated or confidential data. The requirement for user interaction (UI:R) implies that exploitation may depend on a user triggering the vulnerable request, which somewhat limits the attack surface but does not eliminate risk, especially in automated or scripted environments.

MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
