Human-in-the-Loop Safeguards Can Be Forged, Researchers Warn
⚠️ Checkmarx research shows Human-in-the-Loop (HITL) confirmation dialogs can be manipulated so attackers embed malicious instructions into prompts, a technique the researchers call Lies-in-the-Loop (LITL). Attackers can hide or misrepresent dangerous commands by padding payloads, exploiting rendering behaviors like Markdown, or pushing harmful text out of view. Approval dialogs meant as a final safety backstop can thus become an attack surface. Checkmarx urges developers to constrain dialog rendering and validate approved operations; vendors acknowledged the report but did not classify it as a vulnerability.
