A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), OffSeq Mirage (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 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

Red Hat has released updated Grafana packages (version 9.0.9-8.el9_2) that fix these vulnerabilities. Users should apply the provided security update as described in the Red Hat advisory RHSA-2025:8680 and the referenced update article (https://access.redhat.com/articles/11258). No additional mitigation steps are indicated by the vendor beyond applying the update.

Description

Grafana is an open source, feature rich metrics dashboard and graph editor for Graphite, InfluxDB & OpenTSDB. Security Fix(es): * net/http: Request smuggling due to acceptance of invalid chunked data in net/http (CVE-2025-22871) * grafana: Cross-site Scripting (XSS) in Grafana via Custom Frontend Plugins and Open Redirect (CVE-2025-4123) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

Successful exploitation of the request smuggling vulnerability could allow an attacker to interfere with HTTP request processing. The XSS vulnerability could enable attackers to execute arbitrary scripts in the context of the user's browser, potentially leading to session hijacking or other malicious actions. The advisory classifies the overall impact as Important (high severity). There are no known exploits in the wild at the time of the advisory.

Summary

This advisory covers two security flaws in Grafana as packaged for Red Hat Enterprise Linux 9.2. The first is a request smuggling vulnerability in the net/http package caused by acceptance of invalid chunked data (CVE-2025-22871). The second is a cross-site scripting (XSS) vulnerability in Grafana that can be triggered via custom frontend plugins and open redirect vectors (CVE-2025-4123). Red Hat has released updated Grafana packages (version 9.0.9-8.el9_2) that address these issues. The advisory references Red Hat's errata RHSA-2025:8680 and provides links for applying the update.

Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #1OWASP Top 10 A05:2025: Injection (opens in a new tab)
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
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.
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.
Architecture and Design · Implementation · Attack Surface Reduction
Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide…

Base weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product acts as an intermediary HTTP agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed HTTP requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination.
Implementation
Use a web server that employs a strict HTTP parsing procedure, such as Apache.
Implementation
Use only SSL communication.
Implementation
Terminate the client session after each request.
