How We Broke Exchanges: A Deep Dive Into Authentication And Client-Side Bugs
How we broke exchanges: a deep dive into authentication and client-side bugs
Two authentication flaws found auditing exchanges and wallets. Allow-listing localhost as an OAuth origin lets a malicious mobile app run a local web server and complete sign-in silently to capture the token. Separately, a CORS policy allowing credentials from insecure subdomains lets a network attacker tamper with one and read the session token.
