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.
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 (CWE-79) in a public-facing WordPress plugin is directly exploitable via T1190; the reflected input + UI:R requirement (malicious link) also facilitates delivery via T1566.002.
