This vulnerability in Grafana's datasource proxy API allows authorization checks to be bypassed by adding an extra slash character in the URL path. Users with minimal permissions could gain unauthorized read access to GET endpoints in Alertmanager and Prometheus datasources. The issue primarily affects datasources that implement route-specific permissions, including Alertmanager and certain Prometheus-based datasources.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0339 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-8986:
    A vulnerability was found in Grafana's data source proxy API, which allows authorization checks to be     bypassed by adding an extra slash character in the URL path. Users with minimal permissions could gain     unauthorized read access to GET endpoints in Alert manager and Prometheus data sources. The issue     primarily affects data sources that implement route-specific permissions, including Alert manager and     certain Prometheus-based data sources.

    CVE-2024-8118:
    The tokenizer incorrectly interprets tags with unquoted attribute values that end with a solidus character     (/) as self-closing. When directly using Tokenizer, this can result in such tags incorrectly being marked     as self-closing, and when using the Parse functions, this can result in content following such tags as     being placed in the wrong scope during DOM construction, but only when tags are in foreign content (e.g.
    <math>, <svg>, etc contexts).

    CVE-2024-11741:
    The grafana plugin SDK bundles build metadata into the binaries it compiles; this metadata includes the     repository URI for the plugin being built, as retrieved by running `git remote get-url origin`.

    If credentials are included in the repository URI (for instance, to allow for fetching of private     dependencies), the final binary will contain the full URI, including said credentials.

    CVE-2025-22872:
    In Grafana, the wrong permission is applied to the alert rule write API endpoint, allowing users with     permission to write external alert instances to also write alert rules.

    CVE-2025-3454:
    Grafana is an open-source platform for monitoring and observability.
    The Grafana Alerting VictorOps integration was not properly protected and could be exposed to users with     Viewer permission.
    Fixed in versions 11.5.0, 11.4.1, 11.3.3, 11.2.6, 11.1.11, 11.0.11 and 10.4.15

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

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

According to its self-reported version, the Grafana install hosted on the remote host is prior to 10.4.17, or 11.2.x prior to 11.2.8, or 11.3.x prior to 11.3.5, or 11.4.x prior to 11.4.3, or 11.5.x prior to 11.5.3. It is, therefore, affected by an improper authorization.

- Grafana's datasource proxy API allows authorization checks to be bypassed by adding an extra slash character in the URL path.

Note that the scanner has not tested for these issues 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.

  - This vulnerability in Grafana's datasource proxy API allows authorization checks to be bypassed by adding     an extra slash character in the URL path. Users with minimal permissions could gain unauthorized read     access to GET endpoints in Alertmanager and Prometheus datasources. The issue primarily affects     datasources that implement route-specific permissions, including Alertmanager and certain Prometheus-based     datasources. (CVE-2025-3454)

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

The version of Grafana Labs installed on the remote host is affected by improper authorization vulnerability as referenced in the CVE-2025-3454 advisory. 

  - This vulnerability in Grafana's datasource proxy API allows authorization checks to be bypassed by adding     an extra slash character in the URL path.
