Prototype pollution vulnerability in patchmerge versions 1.0.0 through 1.0.1 allows an attacker to cause a denial of service and may lead to remote code execution.

Weakness

The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
