Object prototype members are modified via attacker-controlled keys, altering application behavior.
Freeze prototypes, use null-prototype maps, validate merge/extend keys.
MITRE ATT&CK techniques associated with this weakness class (mapped via MITRE CAPEC). A vulnerability of this type could let an adversary carry out:
A stage-by-stage walkthrough of the attack, mapped to the real MITRE ATT&CK tactics for this weakness — what the attacker is trying to do, what's at risk (what can be stolen or damaged), and how you defend. Understanding the playbook is how you shut it down.
Run attacker-chosen code or commands on the system.
Application logic and the host runtime — an attacker can execute arbitrary code or commands.

Least-privilege runtime, sandboxing, and safe deserialization/parsing.
Gain higher privileges — from a limited account to admin/root.
Over-permissioned services, weak file/permission boundaries, and setuid paths.
Drop privileges, enforce least privilege, and lock down file permissions.
This is a defensive, conceptual walkthrough for education — stages reflect MITRE ATT&CK tactics associated with this weakness class, not a working exploit. Not every attack uses every stage.
