CVE-2026-54136

Summary A resource-scoped API token can read script contents outside its allowed path scope via GET /api/w/{workspace}/scripts/list_search. This appears to be a remaining variant of the scoped-token authorization class previously addressed for other endpoints. The route-level scope middleware validates the token domain/action, but does not enforce the resource/path segment of a scope. scripts/list_search then returns script path and content for scripts in the workspace without applying per-row path filtering against the token scopes. Affected endpoint GET /api/w/{workspace}/scripts/list_search Affected versions Confirmed in the current public repository code and believed to affect the latest published release at the time of review: <= 1.714.1 Patched version: unknown. Details Windmill supports scoped API tokens with scopes in the format: {domain}:{action}[:{resource}] The parser supports resource-scoped values such as: scripts:read:f/allowed/* and the codebase contains helpers for resource matching, including wildcard matching. However, the route-level scope check used for requests with scoped API tokens only validates the route domain and action. It does not compare the token's resource/path restriction against the requested route or against the rows returned by list endpoints. For scripts/list_search, the handler returns path and content for scripts in the workspace: SELECT path, content from script WHERE workspace_id = $1 AND archived = false LIMIT $2 There is no additional check_scopes(...) call in the handler and no per-row filtering based on the token's resource/path scope. As a result, a token intended to read only scripts under one path prefix may be able to read script contents from unrelated paths in the same workspace. Source-level reproduction 1. Create or use a workspace containing at least two scripts: - f/allowed/script_a - f/private/script_b 2. Create a scoped API token intended to read only the allowed path: scripts:read:f/al
