How to fix?

Upgrade ejs to version 3.1.10 or higher.

Overview

ejs is a popular JavaScript templating engine.

Affected versions of this package are vulnerable to Improper Control of Dynamically-Managed Code Resources due to the lack of certain pollution protection mechanisms. An attacker can exploit this vulnerability to manipulate object properties that should not be accessible or modifiable.

Note:

Even after updating to the fix version that adds enhanced protection against prototype pollution, it is still possible to override the hasOwnProperty method.
