GPT-5 AI Router Novel Vulnerability Class Exposes the Fatal Flaw in Multi-Model Architectures - adversa.ai/blog/promisqroute… by @Adversa_AI Security researchers from Adversa AI  discovered that ChatGPT 5 have a fatal flaw: they can route your requests to cheaper, less secure models to save money. Attackers can exploit this to bypass AI security and safety measures with just a few words. What Is PROMISQROUTE? When you use ChatGPT or any major AI service, you think you’re talking to one AI model. You’re not. Behind the scenes, a “router” reads your message and decides which of many models should answer—usually picking the cheapest one, not the safest. Meet PROMISQROUTE — a fundamentally new AI vulnerability that abuses AI routing mechanism to trigger SSRF-style bypass in multimodal infrastructure leading to ChatGPT Model Downgrade and Jailbreak exploitation as an example. The real answer to WHY its was so easy to Jailbreak GPT-5 PROMISQROUTE = Prompt-based Router Open-Mode Manipulation Induced via SSRF-like Queries, Reconfiguring Operations Using Trust Evasion.
