MITRE ATT&CK Enterprise TechniquesAI

T1059.007 JavaScript Execution
Adversaries may abuse various implementations of JavaScript for execution.
T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1659 Content Injection Initial Access
Adversaries may gain access and continuously communicate with victims by injecting malicious content into systems through online network traffic.
Why these techniques?

Stored XSS enables injection of arbitrary JavaScript into WordPress pages (T1659: Content Injection), exploitation of the public-facing web application (T1190), and execution of JavaScript in users' browsers (T1059.007).
