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 3 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.

What to do

AI-suggested

Red Hat has released updated Grafana packages (version 10.2.6-17.el10_0) for Red Hat Enterprise Linux 10 and its Extended Update Support variants. Users should apply these official updates promptly to remediate the vulnerability. Detailed update instructions are available in the Red Hat advisory and article linked in the vendor advisory content. No additional mitigation steps are indicated beyond applying the official patches.

Description

A security update for Grafana addresses a Cross-site Scripting (XSS) vulnerability and an Open Redirect issue identified as CVE-2025-4123. The vulnerability involves custom frontend plugins in Grafana, an open source metrics dashboard and graph editor. Red Hat has released patches for multiple versions of Red Hat Enterprise Linux 10 to remediate this issue.

Impact

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the victim's browser via XSS, potentially leading to session hijacking, credential theft, or other malicious actions. The Open Redirect component could be used to redirect users to malicious sites. The vulnerability affects multiple Red Hat Enterprise Linux 10 variants and architectures. No known exploitation in the wild has been reported.

Summary

CVE-2025-4123 is a vulnerability in Grafana that allows Cross-site Scripting (XSS) attacks via custom frontend plugins and includes an Open Redirect flaw. This vulnerability affects Grafana as packaged in Red Hat Enterprise Linux 10 and its Extended Update Support versions across various architectures. Red Hat has issued security advisories and released updated packages (version 10.2.6-17.el10_0) to fix this issue. Public exploit code is available on Exploit-DB, and detection templates exist for automated scanning. The vulnerability is rated as having an important security impact by Red Hat, with a high severity rating in this analysis.

Public tooling indexed from Metasploit Framework, Exploit-DB, ProjectDiscovery nuclei-templates and PoC-in-GitHub. Its existence raises the odds of exploitation; it does not confirm attacks.
