According to its self-reported version, the Grafana install hosted on the remote host is prior to 11.6.14, or 12.1.x prior to 12.1.10, or 12.2.x prior to 12.2.8, or 12.3.x prior to 12.3.6, or 12.4.x prior to 12.4.2. It is, therefore, affected by multiple vulnerabilities.

- Grafana's SQL expressions feature enables transforming query data with familiar SQL syntax. A vulnerability in this feature allows arbitrary file write enabling remote code execution.

- Grafana's OpenFeature feature flag validation endpoints do not require authentication and accept unbounded user input, leading to an unauthenticated denial-of-service.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Grafana installed on the remote host is 12.1.x prior to 12.1.10, 12.2.x prior to 12.2.8, 12.3.x prior to 12.3.6, or 12.4.x prior to 12.4.2. It is, therefore, affected by a denial of service vulnerability:

  - The OpenFeature feature toggle evaluation endpoint reads unbounded values into memory, which can cause     out-of-memory crashes. (CVE-2026-27880)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 138319f3-5901-11f1-b525-3c7c3fba4204 advisory.

    https://grafana.com/security/security-advisories/cve-2026-27880 reports:
    The OpenFeature feature toggle evaluation endpoint reads unbounded               values into memory, which can cause out-of-memory crashes.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The OpenFeature feature toggle evaluation endpoint reads unbounded values into memory, which can cause     out-of-memory crashes. (CVE-2026-27880)

Note that Nessus relies on the presence of the package as reported by the vendor.
