CVE-2026-63309 Details

ANALYZED

This CVE record has been analyzed and enriched by NVDAPI.com as an independent party.

Description

SurrealDB before 3.1.5 fail to apply field-level SELECT permissions to ORDER BY clauses, allowing authenticated users to leak the relative ordering of restricted field values. Attackers can issue ORDER BY queries on indexed restricted fields to recover the hidden values' sort order across records, even though the field itself returns null as intended.
