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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
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: 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: 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 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

To mitigate CVE-2025-68386, organizations should first verify the Kibana versions in use and plan for an upgrade to patched versions once available from Elastic. In the absence of patches, implement strict role-based access controls (RBAC) to limit the number of users with permissions to modify document sharing settings. Audit existing user roles and permissions to ensure the principle of least privilege is enforced. Monitor Kibana logs for unusual HTTP requests that attempt to change sharing settings, focusing on anomalous patterns or requests from unexpected users. Consider network segmentation to restrict access to Kibana interfaces only to trusted users and systems. Employ multi-factor authentication (MFA) to reduce the risk of account compromise. Additionally, educate users about the risks of privilege escalation and enforce strong password policies. Regularly review and update security policies related to Kibana usage and document sharing. Finally, maintain an incident response plan to quickly address any detected exploitation attempts.

Description

Improper Authorization (CWE-285) in Kibana can lead to privilege escalation (CAPEC-233) by allowing an authenticated user to change a document's sharing type to "global," even though they do not have permission to do so, making it visible to everyone in the space via a crafted a HTTP request.

Impact

For European organizations, this vulnerability can lead to unauthorized modification of document sharing settings within Kibana, resulting in broader visibility of sensitive dashboards or reports than intended. While it does not directly compromise data confidentiality or system availability, the integrity of access controls is compromised, potentially exposing sensitive operational data to unauthorized users within the same Kibana space. This can affect decision-making processes, compliance with data protection regulations such as GDPR, and overall security posture. Organizations in sectors such as finance, energy, telecommunications, and government that use Kibana for critical monitoring and analytics are particularly at risk. The vulnerability could be exploited by malicious insiders or compromised accounts to escalate privileges and access sensitive information. The absence of known exploits in the wild reduces immediate risk, but the ease of exploitation by any authenticated user necessitates prompt mitigation to prevent potential misuse.

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.
