Summary
CVE-2023-22462 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Grafana Grafana. Its CVSS base score is 6.4 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 25% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Grafana, an open-source monitoring and observability platform, contains a stored cross-site scripting vulnerability in its core Text plugin. The flaw stems from React's render cycle temporarily passing unsanitized HTML before it is cleaned and persisted to the database, allowing an Editor-privileged user to embed executable JavaScript in a Text panel. The issue is tracked as CWE-79 with a CVSS 3.1 score of 6.4.
An attacker with the Editor role can modify a Text panel to include malicious JavaScript. When a second user, such as one holding the Admin role, subsequently edits the same panel and selects the Markdown or HTML view, the script executes in that user's browser context. This interaction enables vertical privilege escalation, for example by capturing or resetting credentials of higher-privileged accounts.
The vulnerability was addressed in Grafana releases 9.2.10 and 9.3.4. Official advisories, including the GitHub Security Advisory GHSA-7rqg-hjwc-6mjf and the Grafana security blog post of 28 February 2023, recommend upgrading to these or later versions; NetApp has also published a corresponding advisory (NTAP-20230413-0004).
EPSS scores have remained in a narrow band between 0.1776 and a peak of 0.2005, indicating moderate but stable exploitation interest since disclosure.

interactions in order to be fully exploited. The vulnerability was possible due to React's render cycle that will pass though the unsanitized HTML code, but in the next cycle the HTML is cleaned up and saved in Grafana's database. An attacker needs to have the Editor role in order to change a Text panel to include JavaScript. Another user needs to edit the same Text panel, and click on "Markdown" or "HTML" for the code to be executed. This means that vertical privilege escalation is possible, where a user with Editor role can change to a known password for a user having Admin role if the user with Admin role executes malicious JavaScript viewing a dashboard. This issue has been patched in versions 9.2.10 and 9.3.4.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.
Validates web inputs to reject script-related content that could produce XSS.
Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).
Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).

A.5.6 only promotes membership in groups to improve knowledge, receive alerts, and share information; it performs no action that stops XSS exploitation (or even the underlying neutralization defect) and is a pure dependency for other controls per the owner's labeling rule.
