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.
T1204.001 Malicious Link Execution
An adversary may rely upon a user clicking a malicious link in order to gain execution.
Why these techniques?

Reflected XSS in public-facing WordPress theme directly enables T1190 (exploit of public-facing app via crafted input) and requires user interaction with malicious link (T1204.001) to trigger payload execution in browser.
