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.

Exploitation evidence

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

Restrict access to Kibana interfaces to trusted networks and authenticated users only, minimizing exposure to untrusted actors.
Implement strict URL validation and filtering at reverse proxies or web application firewalls (WAFs) to detect and block suspicious redirect parameters.
Monitor Kibana logs for unusual redirect patterns or unexpected outbound requests indicative of SSRF attempts.
Apply the principle of least privilege for Kibana user roles to limit who can generate or manipulate URLs that trigger redirects.
Isolate Kibana servers from sensitive internal services to reduce SSRF impact, using network segmentation and firewall rules.
Stay alert for official patches or updates from Elastic and apply them promptly once available.
Educate users about the risks of clicking on unexpected Kibana URLs, especially those received via email or external sources.
Consider deploying runtime application self-protection (RASP) or endpoint detection tools that can detect anomalous redirect or SSRF behaviors in real time.

Description

URL redirection to an untrusted site ('Open Redirect') in Kibana can lead to sending a user to an arbitrary site and server-side request forgery via a specially crafted URL.

Impact

For European organizations, this vulnerability poses a moderate risk primarily to the integrity of their Kibana deployments. Since Kibana is widely used for monitoring, logging, and data visualization across industries including finance, telecommunications, and government, an open redirect could be exploited to redirect users to phishing or malware-hosting sites, increasing the risk of credential theft or malware infection. The SSRF aspect could allow attackers to access internal services behind firewalls, potentially exposing sensitive data or enabling lateral movement within networks. Although the vulnerability does not directly impact confidentiality or availability, the indirect effects of SSRF and user redirection could lead to data breaches or compromise of internal infrastructure. Organizations relying heavily on Kibana for operational intelligence or compliance reporting may face disruptions or reputational damage if exploited. The medium severity rating suggests that while immediate catastrophic impact is unlikely, targeted attacks against critical infrastructure or sensitive environments could have serious consequences.

CWE-601URL Redirection to Untrusted Site ('Open Redirect') (opens in a new tab)
Base weaknessLikelihood of exploit: LowOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
Use an intermediate disclaimer page that provides the user with a clear warning that they are leaving the current site. Implement a long timeout before the redirect occurs, or force the user to click on the link. Be careful to avoid XSS problems (CWE-79) when generating the disclaimer page.
Architecture and Design · Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
