How to fix?

Upgrade ses to version 0.16.0 or higher.

Overview

ses is a secure runtime for running third-party code safely.

Affected versions of this package are vulnerable to Improper Data Handling due to a defect in harden properties which have names that parse as numbers but are not the same as the canonical representation of those numbers, as in "+0" and "" which are both equivalent to their canonical number "0", remain writable after hardening.

Workaround

Users who are unable to upgrade to the fixed version should avoid sharing TypedArrays between co-tenant programs and instead create wrapper objects that produce a read-only view of the underlying data.
