## What is CVE-2026-32252?

CVE-2026-32252 is a high-severity missing authorization vulnerability in chartbrew, published on 10 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to 4.9.0, a cross-tenant authorization bypass exists in Chartbrew in GET /team/:team_id/template/generate/:project_id. The GET handler calls checkAccess(req, "updateAny", "chart") without awaiting the returned promise, and it does not verify that the supplied project_id belongs to req.params.team_id or to the caller's team. As a result, an authenticated attacker with valid template-generation permissions in their own team can request the template model for a project belonging to another team and receive victim project data. This vulnerability is fixed in 4.9.0.

Weakness: CWE-285 (Improper Authorization)

Check this codebase for CVE-2026-32252 and fix it if it is affected.

What it is: CVE-2026-32252 is a high-severity missing authorization vulnerability in chartbrew, published on 10 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-32252 exists.

Affected product: chartbrew. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
