# CVE-2020-13379: Server Side Request Forgery in Grafana > Unauthenticated attackers can exploit Grafana's avatar feature to perform Server-Side Request Forgery, accessing internal network resources and causing denial of service. - **Severity:** High 8.2 (`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 3 Jun 2020 - **Updated:** 4 Aug 2024 - **Also known as:** BIT-grafana-2020-13379, GHSA-wc9w-wvq2-ffm9, RHSA-2020:2641, RHSA-2020:2676, RHSA-2020:5599 ## What is CVE-2020-13379? CVE-2020-13379 is a high-severity server-side request forgery vulnerability in Fedoraproject Fedora, published on 3 Jun 2020. An attacker can exploit it over the internet without logging in, with no action from the victim. ### 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.

Affected packages and fixed versions: - github.com/grafana/grafana (Go): affected from 3.0.1; fixed in 6.7.4 - github.com/grafana/grafana (Go): affected from 3.0.1; fixed in 6.7.4 - github.com/grafana/grafana (Go): affected from 7.0.0; fixed in 7.0.2 - github.com/grafana/grafana (Go): affected from 7.0.0; fixed in 7.0.2 - grafana (Bitnami): affected from 3.0.1; fixed in 7.0.2 Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
