CVE-2020-13379: SSRF

First published: Wed Jun 03 2020(Updated: )

An SSRF incorrect access control vulnerability was found in Grafana regarding the avatar feature, allowing any unauthenticated user or client to make Grafana send HTTP requests to any URL and then return its result to the user or client. Additionally, the same issue can create a NULL pointer dereference vulnerability. This flaw allows an attacker to gain information about the network that Grafana is running on, or cause a segmentation fault, resulting in a denial of service.
