# CVE-2022-21702: Cross site scripting in Grafana proxy > An attacker can execute cross-site scripting attacks in Grafana by tricking authenticated users into visiting crafted links via compromised datasources or plugins. - **Severity:** Medium 6.5 (`CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:L/A:N`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Over the internet - **Victim action needed:** A user has to click or open something - **Fix available:** Yes - **Published:** 8 Feb 2022 - **Updated:** 22 Apr 2025 - **Also known as:** BIT-grafana-2022-21702, GHSA-xc3p-28hw-q24g, OESA-2022-1599, OESA-2022-2077, UBUNTU-CVE-2022-21702 ## What is CVE-2022-21702? CVE-2022-21702 is a medium-severity cross-site scripting vulnerability in Fedoraproject Fedora, published on 8 Feb 2022. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link. ### Official description Grafana is an open-source platform for monitoring and observability. In affected versions an attacker could serve HTML content thru the Grafana datasource or plugin proxy and trick a user to visit this HTML page using a specially crafted link and execute a Cross-site Scripting (XSS) attack. The attacker could either compromise an existing datasource for a specific Grafana instance or either set up its own public service and instruct anyone to set it up in their Grafana instance. To be impacted, all of the following must be applicable. For the data source proxy: A Grafana HTTP-based datasource configured with Server as Access Mode and a URL set, the attacker has to be in control of the HTTP server serving the URL of above datasource, and a specially crafted link pointing at the attacker controlled data source must be clicked on by an authenticated user. For the plugin proxy: A Grafana HTTP-based app plugin configured and enabled with a URL set, the attacker has to be in control of the HTTP server serving the URL of above app, and a specially crafted link pointing at the attacker controlled plugin must be clocked on by an authenticated user. For the backend plugin resource: An attacker must be able to navigate an authenticated user to a compromised plugin through a crafted link. Users are advised to update to a patched version. There are no known workarounds for this vulnerability.

Affected packages and fixed versions: - github.com/grafana/grafana (Go): affected from 2.0.0-beta1; fixed in 7.5.15 - github.com/grafana/grafana (Go): affected from 2.0.0-beta1; fixed in 7.5.15 - github.com/grafana/grafana (Go): affected from 8.0.0; fixed in 8.3.5 - github.com/grafana/grafana (Go): affected from 8.0.0; fixed in 8.3.5 - grafana (Bitnami): affected from 2.0.1; fixed in 7.5.15, 8.3.5 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.
