NewCVE-2026-63755 (opens in a new tab)How to fix?
Upgrade surrealdb to version 3.1.0-beta.1 or higher.
Overview
Affected versions of this package are vulnerable to Incorrect Authorization in the evaluation of user-supplied expressions in WHERE, SET, MERGE, CONTENT, and PATCH clauses before permission checks are enforced. An attacker can access unauthorized table data by crafting queries that exploit the order of operations, potentially exfiltrating sensitive information through scripting functions, SurrealQL's THROW statement, or timing-based side channels. This is only exploitable if the attacker is authenticated to the target database; cross-database or cross-namespace access is not possible.
Workaround
This vulnerability can be mitigated by disabling scripting functions (removing the -A / --allow-scripting flag), limiting query access for untrusted users, and using namespace/database isolation as the primary security boundary.
