r/cybersecurity: Every SaaS Company Is Accidentally Building the Same AI Privilege-Escalation Vulnerability That Hit Meta Instagram

Security blog AgileHunt argues the attack vector behind the Meta Instagram AI chatbot account takeovers — AI support agents granted elevated account-management privileges that can be socially engineered into adding attacker-controlled credentials and resetting passwords — is a systemic design flaw replicated across SaaS products. The analysis contends any AI assistant with the ability to modify account settings, reset credentials, or execute privileged operations creates an exploitable attack surface by construction, not configuration. The post advocates a separation-of-duties model where AI agents can query but not execute privileged operations without a human-in-the-loop confirmation step.
