Synopsis

The web application running on the remote web server is affected by a restriction bypass vulnerability.

Description

According to its self-reported version number, the version of Grafana Enterprise running on the remote host is a version 9.4.x prior to 9.4.17, 9.5.x prior to 9.5.13, 10.0.x prior to 10.0.9 or 10.1.x prior to 10.1.5. It is, therefore, affected by a restriction bypass vulnerability.

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