CVE-2026-63745

MediumCVSS 5.4/10Last modified Oct 8, 2026

Description

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.
