CVE-2026-63745: Surrealdb

Medium severity, CVSS 5.4. EPSS: 0.2% chance of exploitation in the next 30 days.

SurrealDB versions before 3.1.0 contain an authorization bypass vulnerability where authenticated users can spoof composite record-id field values by writing to editable body fields. Attackers can bypass permission rules that gate access on id components like tenant isolation by setting same-named body fields to spoofed values that permission checks incorrectly read instead of the immutable id key.
