| Título | brikcss @brikcss/merge 1.3.0 Prototype Pollution |
|---|
| Descrição | The @brikcss/merge package is vulnerable to Prototype Pollution - a critical security vulnerability that allows attackers to inject arbitrary properties into JavaScript's global object prototype. This occurs because the merge function recursively processes objects without properly sanitizing special keys like __proto__, constructor.prototype, and prototype.
When an attacker controls the source object being merged, they can inject properties into Object.prototype, affecting all objects in the application.
