Integrity: Low
Availability: None

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

Disclosed: evidence found.
CVE published 13 May 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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 12 Nov 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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

A fixed version of Grafana is available: 11.6.14+security-04. Users should upgrade to this version to remediate the vulnerabilities. The Red Hat advisories for the Multicluster Global Hub include updated container images and security fixes. Applying these updates as per vendor guidance will mitigate the identified risks. No additional mitigation steps are specified or required beyond applying the official fixes.

Description

Multiple vulnerabilities have been identified in Grafana, an analysis and visualization software. These issues affect versions prior to 11.6.14+security-04 and the specific version 11.6.14+security-04. The vulnerabilities have been addressed in the fixed version 11.6.14+security-04. Red Hat advisories related to the Multicluster Global Hub, which includes Grafana components, indicate important security updates but do not specify individual fixes for these Grafana vulnerabilities. No known exploits in the wild have been reported.

Impact

The vulnerabilities affect Grafana's security posture, potentially exposing systems running affected versions to risks that have not been explicitly detailed in the provided data. The Red Hat advisories rate the related updates as having an important security impact, indicating that the vulnerabilities could lead to significant security issues if left unpatched. However, no active exploitation has been reported.

Summary

This report covers multiple security vulnerabilities in Grafana, a data visualization and analytics platform. The affected versions include all releases before 11.6.14+security-04 and the exact version 11.6.14+security-04. The Bundesamt für Sicherheit in der Informationstechnik (BSI) identifies these vulnerabilities under CVE-2026-28374 and related CVEs. Red Hat advisories for the Multicluster Global Hub, which bundles Grafana, mention security updates rated as important but do not detail specific fixes for these vulnerabilities. The fixed Grafana version is 11.6.14+security-04. There is no evidence of exploitation in the wild. The advisories provide references and updated container images for remediation.
