CVE-2024-28251Network attack vector

DataDoc access via unrestricted WebSocket origins

Published Mar 13, 2024 · Updated Aug 2, 2024

Cross-site WebSocket hijacking in Pinterest Querybook before 3.32.0 allows remote attackers to read, edit, or delete DataDocs. The make_socketio function passes a wildcard to cors_allowed_origins, causing production to accept WebSocket handshakes from untrusted origins. Exploitation requires an attacker-controlled origin to reach the endpoint in a user's browser session, exposing or altering DataDoc cells and query activity.
