CVE-2025-64753 Details
Description
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.
A vulnerability exists in Grist-Core versions prior to 1.7.6, allowing users with partial read access to documents to access the '/compare' endpoint. This endpoint could be used to retrieve hashes of document versions and a complete list of changes between those versions, including details about cells, columns, or tables that the user was not authorized to view. The issue has been addressed in version 1.7.6 by restricting the '/compare' endpoint to users with full read access.
Users are advised to upgrade to Grist-Core version 1.7.6 or later. For those unable to upgrade, sensitive document history can be removed using the '/states/remove' endpoint, or the '/compare' endpoint can be blocked.
