CVE-2026-63740: Surrealdb

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Surrealdb Surrealdb: before 3.1.4 (fixed in 3.1.4)
