Grafana: >> Grafana >> 10.0.6 Security Vulnerabilities
Public dashboards with annotations enabled did not limit their annotation timerange to the locked timerange of the public dashboard. This means one could read the entire history of annotations visible on the specific dashboard, even those outside the locked timerange.
This did not leak any annotations that would not otherwise be visible on the public dashboard.

Every uncached /avatar/:hash request spawns a goroutine that refreshes the Gravatar image. If the refresh sits in the 10-slot worker queue longer than three seconds, the handler times out and stops listening for the result, so that goroutine blocks forever trying to send on an unbuffered channel. Sustained traffic with random hashes keeps tripping this timeout, so goroutine count grows linearly, eventually exhausting memory and causing Grafana to crash on some systems.

A cross-site scripting (XSS) vulnerability exists in Grafana caused by combining a client path traversal and open redirect. This allows attackers to redirect users to a website that hosts a frontend plugin that will execute arbitrary JavaScript. This vulnerability does not require editor permissions and if anonymous access is enabled, the XSS will work. If the Grafana Image Renderer plugin is installed, it is possible to exploit the open redirect to achieve a full read SSRF.
The default Content-Security-Policy (CSP) in Grafana will block the XSS though the `connect-src` directive.

Grafana is an open-source platform for monitoring and observability.
In Grafana Enterprise, Request security is a deny list that allows admins to configure Grafana in a way so that the instance doesn’t call specific hosts.
However, the restriction can be bypassed used punycode encoding of the characters in the request address.

Grafana is an open-source platform for monitoring and observability. The vulnerability impacts Grafana instances with several organizations, and allows a user with Organization Admin permissions in one organization to change the permissions associated with Organization Viewer, Organization Editor and Organization Admin roles in all organizations.
It also allows an Organization Admin to assign or revoke any permissions that they have to any user globally.
This means that any Organization Admin can elevate their own permissions in any organization that they are already a member of, or elevate or restrict the permissions of any other user.
The vulnerability does not allow a user to become a member of an organization that they are not already a member of, or to add any other users to an organization that the current user is not a member of.
