## Overview

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.

## Affected

- `surrealdb >= 2.0.0 < 3.3.1`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
