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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
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: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Immediately audit and restrict update permissions on User resources within Rancher to only trusted administrators to reduce the attack surface.
Implement strict role-based access control (RBAC) policies that limit who can update user accounts, ensuring the principle of least privilege is enforced.
Monitor Rancher logs for unusual update activities on user accounts, especially changes to the `.username` field.
Apply network segmentation and isolate Rancher management interfaces to trusted networks and VPNs to reduce exposure.
Stay alert for official patches or updates from SUSE and apply them promptly once available.
Consider implementing additional multi-factor authentication (MFA) for administrative users to reduce risk of compromised credentials being used to exploit this vulnerability.
Develop incident response plans that include procedures for quickly restoring access to affected user accounts if denial of access is detected.
If possible, test Rancher environments in staging to identify if this vulnerability can be exploited internally and validate mitigation effectiveness before production deployment.

Description

A vulnerability has been identified within Rancher Manager where a missing server-side validation on the `.username` field in Rancher can allow users with update permissions on other User resources to cause denial of access for targeted accounts.

Impact

For European organizations, the impact of this vulnerability can be significant, especially for those using Rancher to manage Kubernetes clusters and containerized workloads. The ability for an attacker with update permissions to deny access to other user accounts can disrupt operational continuity, delay incident response, and potentially block critical administrative actions. This could lead to downtime or degraded service availability, impacting business operations and service delivery. In regulated industries such as finance, healthcare, or critical infrastructure, such disruptions could also lead to compliance violations or impact service-level agreements. Since Rancher is often integrated into complex cloud-native environments, this vulnerability could also complicate multi-tenant or multi-user environments, increasing the risk of insider threats or privilege abuse. The lack of confidentiality impact reduces the risk of data leakage, but the availability impact alone is sufficient to cause operational and reputational damage.

CWE-863Incorrect Authorization (opens in a new tab)
Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #17OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
