CVE-2026-54136Network attack vectorHinoki check available

Script disclosure via missing path-scope enforcement

Published Aug 20, 2026 · Updated Aug 20, 2026

Incorrect authorization in Windmill before 1.715.0 allows remote authenticated users to read script contents via scripts/list_search. The route-level scope check accepts scoped tokens based only on domain and action, and the list_search_scripts handler returns script path and content without enforcing the token's resource path or filtering rows. Exploitation requires a valid workspace API token such as a path-restricted scripts:read scope and exposes source code from other paths in the same workspace, including embedded configuration or secrets.
