    Published: 3 Nov 2026Last Modified: 5 Nov 2026

    Summary: SurrealDB 2.0.0 before 3.3.1 deny-funcs Capability Bypass via Method-Style Invocations

    Details: SurrealDB 2.0.0 before 3.3.1 does not enforce --deny-funcs restrictions on method-style function calls in the streaming engine, because MethodPart::evaluate invokes resolved functions without a capability check. Authenticated users who can submit queries can run denied functions via method syntax, e.g. [1,2].map() or $f.put()/$f.get() to write and read file bucket data despite file::* denials.
