## What is CVE-2026-25877?

CVE-2026-25877 is a medium-severity missing authorization vulnerability in chartbrew, published on 6 Mar 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 version 4.8.1, the application performs authorization checks based solely on the project_id parameter when handling chart-related operations (update, delete, etc.). No authorization check is performed against the chart_id itself. This allows an authenticated user who has access to any project to manipulate or access charts belonging to other users/ project. This issue has been patched in version 4.8.1.

Weakness: CWE-639 (Authorization Bypass Through User-Controlled Key), CWE-284 (Improper Access Control)

What it is: CVE-2026-25877 is a medium-severity missing authorization vulnerability in chartbrew, published on 6 Mar 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-25877 in the wild and no public exploit code.

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.
