Which versions of SurrealDB are affected by EUVD-2026-45917?

SurrealDB versions before 3.1.0 contain a permission bypass vulnerability allowing authenticated users to circumvent access controls and read restricted database records through relationship…. A patch is available.

How to fix or mitigate EUVD-2026-45917?

Within 24 hours, perform a complete inventory of SurrealDB deployments to identify all instances running versions before 3.1.0, then audit configuration to document which tables are protected with restrictive SELECT permissions and which user roles have legitimate read access to other tables. Within 7 days, implement database access monitoring to detect and alert on unusual access patterns to permission-restricted tables, and apply the principle of least privilege across all database users to limit access to only the tables necessary for their business function. Within 30 days, subscribe to SurrealDB vendor advisories for version 3.1.0 release, test the patched version in a non-production environment to verify permission enforcement, and establish a timeline for upgrading all affected instances with appropriate change management.

HIGH 7.1

DescriptionCVE.org

SurrealDB versions before 3.1.0 fail to enforce table SELECT permissions when traversing graph edges or back-references. Authenticated users can read records from any table reachable through graph edges regardless of the target table's PERMISSIONS FOR select clause.

AnalysisAI

Information disclosure in SurrealDB before 3.1.0 allows authenticated record or scope users to bypass table-level SELECT permissions by traversing graph edges or REFERENCES TO back-references, reading full documents from tables defined with PERMISSIONS FOR select NONE. The root cause is that GraphEdgeScan and ReferenceScan fetched records directly from storage without evaluating the target table's permission expression. …
