## What is CVE-2022-39306?

CVE-2022-39306 is a medium-severity vulnerability in Grafana Grafana, published on 9 Nov 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. Versions prior to 9.2.4, or 8.5.15 on the 8.X branch, are subject to Improper Input Validation. Grafana admins can invite other members to the organization they are an admin for. When admins add members to the organization, non existing users get an email invite, existing members are added directly to the organization. When an invite link is sent, it allows users to sign up with whatever username/email address the user chooses and become a member of the organization. This introduces a vulnerability which can be used with malicious intent. This issue is patched in version 9.2.4, and has been backported to 8.5.15. There are no known workarounds.

Weakness: CWE-20 (Improper Input Validation)

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.
