AI Analysis

No AI analysis yet.

Description

SurrealDB versions before 3.2.0 contain a permissions bypass vulnerability where data-modifying statements within PERMISSIONS clauses execute with enforcement disabled. Attackers with permission to perform a guarded operation can write to tables they lack permission for by embedding CREATE, UPDATE, DELETE, or UPSERT statements in the PERMISSIONS clause, causing unintended writes and data corruption.
