CVE-2025-4123 is a high-severity cross-site scripting vulnerability in Grafana Grafana, published on 22 May 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link. ### Official description A cross-site scripting (XSS) vulnerability exists in Grafana caused by combining a client path traversal and open redirect. This allows attackers to redirect users to a website that hosts a frontend plugin that will execute arbitrary JavaScript. This vulnerability does not require editor permissions and if anonymous access is enabled, the XSS will work. If the Grafana Image Renderer plugin is installed, it is possible to exploit the open redirect to achieve a full read SSRF. The default Content-Security-Policy (CSP) in Grafana will block the XSS though the `connect-src` directive. Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation), CWE-601 (URL Redirection to Untrusted Site) ## Which versions are affected by CVE-2025-4123? 4 open source packages ship an affected version, including github.com/grafana/grafana and grafana.

Affected packages and fixed versions: - github.com/grafana/grafana (Go): affected all versions; no fix listed - github.com/grafana/grafana (Go): affected all versions; fixed in 0.0.0-20250521183405-c7a690348df7 - github.com/grafana/grafana (Go): affected all versions; fixed in 0.0.0-20250521183405-c7a690348df7 - grafana (Bitnami): affected all versions; fixed in 10.4.18, 11.6.1, 12.0.0 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.
