    Prototype Pollution

    js-yaml is a human-friendly data serialization language.

    Affected versions of this package are vulnerable to Prototype Pollution via the merge function. An attacker can alter object prototypes by supplying specially crafted YAML documents containing __proto__ properties. This can lead to unexpected behavior or security issues in applications that process untrusted YAML input.

    How to fix Prototype Pollution?

    Upgrade js-yaml to version 3.14.2, 4.1.1 or higher.

    <3.14.2>=4.0.0 <4.1.1
