CVE-2025-64753

grist-core is a spreadsheet hosting server. Prior to version 1.7.7, a user with only partial read access to a document could still access endpoints listing hashes for versions of that document and receive a full list of changes between versions, even if those changes contained cells, columns, or tables to which the user was not supposed to have read access. This was fixed in version 1.7.7 by restricting the `/compare` endpoint to users with full read access. As a workaround, remove sensitive document history using the `/states/remove` endpoint. Another possibility is to block the `/compare` endpoint.

Summary		(es) grist-core es un servidor de alojamiento de hojas de cálculo. Versiones anteriores a la versión 1.7.7, un usuario con solo acceso de lectura parcial a un documento aún podía acceder a endpoints que listaban los hashes de las versiones de ese documento y recibir una lista completa de cambios entre versiones, incluso si esos cambios contenían celdas, columnas o tablas a las que el usuario no debería haber tenido acceso de lectura. Esto se solucionó en la versión 1.7.7 al restringir el endpoint /compare a usuarios con acceso de lectura completo. Como solución alternativa, elimine el historial de documentos confidenciales usando el endpoint /states/remove. Otra posibilidad es bloquear el endpoint /compare.
