Prototype pollution in Merge-deep
Quick fix
GHSA-r6rj-9ch6-g264 — merge-deep: upgrade to the fixed version with the command below.
npm install merge-deep@3.0.3Details
The merge-deep library before 3.0.3 for Node.js can be tricked into overwriting properties of Object.prototype or adding new properties to it. These properties are then inherited by every object in the program, thus facilitating prototype-pollution attacks against applications using this library.
