What is CVE-2026-63745?

SurrealDB versions prior to 3.1.0 are susceptible to an authorization bypass vulnerability. This flaw enables authenticated users to manipulate composite record-id fields by modifying editable body fields. By doing so, attackers can circumvent established permission rules that are intended to enforce access controls based on unique identifier components, such as tenant isolation. This misconfiguration can lead to unauthorized access and manipulation of sensitive data.
