Security readout for executives and security teams
Plain-English summary
Grafana password reset responses could reveal whether a username or email exists. This is an information exposure issue: attackers may use it to identify valid accounts before phishing, credential stuffing, or other targeted activity. Grafana says the issue is fixed in 9.2.4 and backported to 8.5.15, with no known workarounds.
Executive priority
Treat this as a moderate-priority exposure cleanup. It does not indicate active exploitation or direct takeover, but it can make targeted attacks easier. Prioritize internet-facing Grafana and sensitive monitoring environments, then address embedded or appliance-managed Grafana through vendor advisories.
Technical view
CVE-2022-39307 is a CWE-200 information exposure in Grafana’s forgot-password flow. A reset-email POST could return a distinct “user not found” JSON message for nonexistent accounts, enabling user enumeration. Affected versions are Grafana >=9.0.0-beta1 before 9.2.4 and versions before 8.5.15.
Likely exposure
Exposure is most relevant for Grafana instances with reachable login and password-reset functionality, especially internet-facing deployments. The issue affects both direct Grafana installations and potentially products bundling Grafana, as reflected by the NetApp advisory. The source bundle does not identify specific NetApp product impact details here.
Exploitation context
The sources do not report active exploitation, and the CVE is not listed as KEV in the provided bundle. The business risk is account discovery, which can support later social engineering or credential attacks. This CVE alone is not described as full account compromise.
Researcher notes
The provided data names Grafana as affected and cites patched versions 9.2.4 and 8.5.15. There are no known workarounds in the source bundle. The CVSS vector supplied appears stricter than a simple unauthenticated enumeration description, so rely on vendor advisory details for final risk scoring.
Mitigation direction
- Upgrade Grafana 9.x deployments to 9.2.4 or later.
- Upgrade Grafana 8.x deployments to 8.5.15 or later.
- Review Grafana vendor guidance because no workaround is named.
- Check NetApp advisory guidance for environments using bundled Grafana.
Validation and detection
- Inventory Grafana versions across direct and embedded deployments.
- Flag versions >=9.0.0-beta1 and <9.2.4 as affected.
- Flag Grafana versions <8.5.15 as affected.
- Confirm exposed Grafana login surfaces are running fixed versions.

CWE-200: Information exposure and cloud metadata lookup
Information exposure and SSRF weaknesses can make discovery, cloud metadata, and credential material review relevant. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupCredential and access behavior lookup
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

Exposure of Sensitive Information to an Unauthorized Actor
Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
