CVE-2026-63745 is a medium-severity flaw (CVSS 5.4) affecting surrealdb. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- No elevated risk signals yet
A fixed release or distro patch exists.
