This affects the package @tsed/core before 5.65.7. This vulnerability relates to the deepExtend function which is used as part of the utils directory. Depending on if user input is provided, an attacker can overwrite and pollute the object prototype of a program.

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.
