How to fix?

Upgrade deno_io to version 0.59.0 or higher.

Overview

deno_io is a crate that provides IO primitives for other Deno extensions, this includes stdio streams and abstraction over File System files.

Affected versions of this package are vulnerable to Improper Authorization due to improper handling of file-system operations on privileged files. An attacker can escalate permissions and access or modify system-level files by exploiting the lack of explicit deny flags in command-line arguments.
