Linux Distros Unpatched Vulnerability : CVE-2026-13720

medium Nessus Plugin ID 353331

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

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

 - 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)

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

Solution

There is no known solution at this time.
