CVE-2025-64752Network attack vector

Internal data disclosure via unproxied WebSocket fetch

Published Nov 13, 2025 · Updated Nov 14, 2025

SSRF in Grist Labs grist-core before 1.7.7 allows remote attackers to read network-accessible data through a WebSocket fetch. The WebSocket-accessible fetch URL feature sends attacker-controlled HTTP or HTTPS URLs from the server instead of routing them through the proxy for untrusted requests. Access to any document is sufficient, and reachable internal endpoints expose credentials or other data to the requester.
