CVE-2026-63740

HIGH7.1

SurrealDB before 3.1.4 Array Element Permission Bypass

Published Jul 20, 2026

Modified 2 months ago

Details

SurrealDB versions before 3.1.4 fail to properly enforce SELECT permissions on array elements (field.*) for record users, leaking denied array elements instead of hiding them. Attackers with record scope access can read array elements that element-level permissions should deny by exploiting incorrect index handling during permission filtering.
