[bounty] Bad Ordering, Free OpenAI Credits, and Goodbye Passwords?

We open up this weeks bug bounty podcast with a discussion about Google's recent support for passkeys, tackling some misunderstanding about what they are and how open the platform is. Also some talk towards the end about potential vulnerabilities to look out for. Then we dive into the vulnerabilities for the week, involving bypassing phone validation in OpenAI, a bad origin check enabling abuse of a permissive CORS policy, and an order of operations issue breaking the purpose of sanitization in Oracle's Opera.
