MITRE ATT&CK Enterprise TechniquesAI

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.
T1059.007 JavaScript Execution
Adversaries may abuse various implementations of JavaScript for execution.
T1566.002 Spearphishing Link Initial Access
Adversaries may send spearphishing emails with a malicious link in an attempt to gain access to victim systems.
Why these techniques?

Reflected XSS in public-facing WordPress plugin directly enables T1190 exploitation; arbitrary JS execution maps to T1059.007; delivery requires malicious link consistent with T1566.002.
