## What is CVE-2026-54136?

CVE-2026-54136 is a medium-severity missing authorization vulnerability in windmill-labs windmill, published on 20 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

Windmill is an open-source developer platform for internal code: APIs, background jobs, workflows and UIs. Prior to 1.715.0, a resource-scoped API token could read script contents outside its allowed path scope through GET /api/w/{workspace}/scripts/list_search. The route-level scope middleware validated the token domain and action but did not enforce the resource/path segment, and the list_search_scripts handler had no additional check_scopes call or per-row filtering before returning script path and content fields. A token such as scripts:read:f/allowed/* could therefore receive source code for unrelated paths in the same workspace, potentially disclosing internal automation logic, integration details, business logic, inline configuration, or hardcoded secrets and credentials. Exploitation required possession of a valid scoped API token for the workspace but did not require administrator privileges. This issue is fixed in version 1.715.0.

Weakness: CWE-863 (Incorrect Authorization)

- windmill-api (crates.io): affected all versions; fixed in 1.715.0

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.
