Why these techniques?

Stored XSS in Flowise chatbot logs enables exploitation of public-facing web application (T1190) by injecting malicious HTML/JS via prompts. This executes arbitrary JavaScript in admin browsers upon log viewing (T1059.007) and facilitates stealing admin credentials/tokens from localStorage (T1539), allowing account hijacking.
