Vulnerability from fkie_nvd - Published: 2026-08-20 17:18 - Updated: 2026-10-18 20:10
Severity
5.1 (Medium) - CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N
Summary
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.

Antes de la versi\u00f3n 1.715.0, un token de API con \u00e1mbito de recurso pod\u00eda leer el contenido de los scripts fuera de su \u00e1mbito de ruta permitido a trav\u00e9s de GET /api/w/{workspace}/scripts/list_search. El middleware de \u00e1mbito a nivel de ruta validaba el dominio y la acci\u00f3n del token, pero no aplicaba el segmento de recurso/ruta, y el gestor list_search_scripts no ten\u00eda ninguna llamada adicional a check_scopes ni filtrado por fila antes de devolver los campos de ruta y contenido del script. Un token como scripts:read:f/allowed/* pod\u00eda, por lo tanto, recibir c\u00f3digo fuente para rutas no relacionadas en el mismo espacio de trabajo, revelando potencialmente l\u00f3gica de automatizaci\u00f3n interna, detalles de integraci\u00f3n, l\u00f3gica de negocio, configuraci\u00f3n en l\u00ednea o secretos y credenciales codificados. La explotaci\u00f3n requer\u00eda la posesi\u00f3n de un token de API con \u00e1mbito v\u00e1lido para el espacio de trabajo, pero no requer\u00eda privilegios de administrador. Este problema est\u00e1 solucionado en la versi\u00f3n 1.715.0."
