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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
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: 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

CVE published 29 Oct 2025
Detectable: no evidence on record.
No public nuclei template indexed

No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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

Until an official patch is released, European organizations should implement specific mitigations to reduce risk from CVE-2023-32199: 1) Conduct a thorough audit of all custom GlobalRoles in Rancher, focusing on those with wildcard '*' permissions on resources or non-resource URLs. 2) Avoid using overly permissive wildcard rules in GlobalRoles; instead, apply the principle of least privilege by defining explicit and minimal permissions. 3) After removing or modifying GlobalRoles, manually verify that associated user access to clusters has been revoked by testing access or reviewing audit logs. 4) Implement strict monitoring and alerting on Rancher access logs to detect any anomalous or unauthorized cluster access, especially from users whose roles have been revoked. 5) Enforce multi-factor authentication (MFA) and strong credential hygiene for all users with administrative privileges to reduce risk of account compromise. 6) Limit the number of users with high privilege roles and regularly review role assignments. 7) Stay informed on SUSE Rancher security advisories and apply patches promptly once available. 8) Consider network segmentation and additional Kubernetes RBAC controls to limit the blast radius of any unauthorized access. These steps go beyond generic advice by focusing on role auditing, permission minimization, and active verification of access revocation.

Description

A vulnerability has been identified within Rancher Manager, where after removing a custom GlobalRole that gives administrative access or the corresponding binding, the user still retains access to clusters. This only affects custom Global Roles that have a * on * in * rule for resources or have a * on * rule for non-resource URLs

Impact

For European organizations, the impact of CVE-2023-32199 can be significant, especially those relying on SUSE Rancher for Kubernetes cluster management. Persistent unauthorized access after role removal undermines trust in access control mechanisms, potentially allowing former administrators or compromised accounts to maintain control over critical infrastructure. This can lead to unauthorized deployment or modification of workloads, data leakage, or disruption of services. Given the widespread adoption of Kubernetes and Rancher in cloud-native environments across Europe, sectors such as finance, healthcare, telecommunications, and government could face risks of operational disruption and data breaches. The medium CVSS score reflects limited but meaningful confidentiality, integrity, and availability impacts. The requirement for high privileges and user interaction reduces the likelihood of remote exploitation by external attackers but raises concerns about insider threats or compromised privileged accounts. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability is publicly known.
