An authenticated user with permission to query a SQL data source can bypass the fix for CVE-2026-33375 by injecting the timeGroup macro through a WHERE clause, which Grafana's regex-based macro parsing does not reject. Evaluating the injected macro causes uncontrolled memory consumption that can terminate the Grafana server process, resulting in a denial of service. The Microsoft SQL Server, PostgreSQL, and MySQL data sources are affected.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Only self-managed Grafana instances with Auth Proxy authentication and identity caching enabled (sync_ttl
    greater than zero) are affected. The Auth Proxy cache key concatenated the username and forwarded identity
    attributes without a delimiter, so distinct identities could collide on one key. An authenticated user who
    shapes their own attributes to collide with a higher-privileged user's, while that user's cache entry is
    live, is authenticated as that user, up to Administrator (authentication bypass by spoofing).
    (CVE-2026-14199)

  - When SAML IdP-initiated login is enabled in Grafana Enterprise, the SAML library skips validation of the
    InResponseTo field on all SAML responses, including SP-initiated logins. This removes anti-replay
    protection, allowing an attacker who obtains a valid signed SAML assertion to replay it and gain a session
    as the victim user. Only instances with the allow_idp_initiated SAML setting enabled are affected; this
    setting is off by default and Grafana OSS is not affected. (CVE-2026-12704)

  - An authenticated user can list alert rules stored in folders they are not allowed to read through the
    alert rules API list endpoint. When the set of folders the user may read was empty, the folder restriction
    was dropped and every alert rule in the organization was returned. From Grafana 13.1.0, any user can
    trigger this with a folder filter. The exposed data is rule configuration; data source credentials are not
    exposed. (CVE-2026-13719)

  - An Editor can set file-provisioning metadata (the grafana.app/managedBy, grafana.app/managerId and
    grafana.app/sourcePath annotations) when creating a dashboard through the dashboard API, because these
    fields were stored without an authorization check. The dashboard then appears file-provisioned, and
    administrators can no longer update or delete it through Grafana. The impact is limited to the same
    organization and no data is exposed. (CVE-2026-13720)

    - Build only for SUSE distributions

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

Note that Nessus 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.

  - An authenticated user with permission to query a SQL data source can bypass the fix for CVE-2026-33375 by     injecting the timeGroup macro through a WHERE clause, which Grafana's regex-based macro parsing does not     reject. Evaluating the injected macro causes uncontrolled memory consumption that can terminate the     Grafana server process, resulting in a denial of service. The Microsoft SQL Server, PostgreSQL, and MySQL     data sources are affected. (CVE-2026-19475)

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