What is CVE-2026-121416?

SurrealDB versions prior to 3.3.1 lack proper enforcement of restrictions for method-style function calls. This vulnerability allows authenticated users to bypass --deny-funcs restrictions, enabling them to execute unauthorized functions using method syntax. As a result, users can access and manipulate file bucket data that should be restricted, compromising the integrity of the data and overall security of the application.
