What is CVE-2025-64752?

CVE-2025-64752 is a medium-severity server-side request forgery vulnerability in gristlabs grist-core, published on 13 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

grist-core is a spreadsheet hosting server. Prior to version 1.7.7, a user with access to any document on a Grist installation can use a feature for fetching from a URL that is executed on the server. The privileged network access of server-side requests could offer opportunities for attack escalation. This issue is fixed in version 1.7.7. The mitigation was to use the proxy for untrusted fetches intended for such purposes. As a workaround, avoid making http/https endpoints available to an instance running Grist that expose credentials or operate without credentials.

Weakness: CWE-918
