Summary

SurrealDB from 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 runs resolved functions without a capability check. An authenticated user who can submit queries can run denied functions such as file::* through method syntax, reading and writing file bucket data. This is classified as CWE-284, Improper Access Control.

Description from the CNA

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.
