Detailsinfo

A vulnerability has been found in gristlabs grist-core up to 1.7.6 and classified as problematic. Affected by this vulnerability is an unknown function of the file /compare. The manipulation with an unknown input leads to a authorization vulnerability. The CWE definition for the vulnerability is CWE-863. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions. As an impact it is known to affect confidentiality. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is known as CVE-2025-64753 since 11/10/2025. The exploitation appears to be difficult. The attack can be launched remotely. Technical details are known, but no exploit is available.
