CVE-2020-13379

CWE-918Published: June 3, 2020· Updated: Jun 17, 2026

8.2

CVSS v3.1

Official Description

The avatar feature in Grafana 3.0.1 through 7.0.1 has an SSRF Incorrect Access Control issue. This vulnerability allows any unauthenticated user/client to make Grafana send HTTP requests to any URL and return its result to the user/client. This can be used to gain information about the network that Grafana is running on. Furthermore, passing invalid URL objects could be used for DOS'ing Grafana via SegFault.

Technical Analysis

CVE-2020-13379 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in availability disruption (denial of service), with a CVSS base score of 8.2.

A proof-of-concept (PoC) exploit exists for CVE-2020-13379. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
