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 for Red Hat Enterprise Linux 8.4 that address this vulnerability. Users should apply the security update as described in the Red Hat advisory RHSA-2025:8683 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patch.

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 arises via custom frontend plugins in Grafana, an open source metrics dashboard and graph editor. Red Hat has issued an important security advisory for Red Hat Enterprise Linux 8.4 with updated Grafana packages to remediate this issue.

Impact

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the user's browser via XSS, potentially leading to session hijacking or other malicious actions. The open redirect vulnerability could be used to redirect users to malicious sites. The issue affects Grafana installations using custom frontend plugins. The vulnerability is rated with high severity by Red Hat.

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.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
