OAuth bug bounty strategy, hunt the application side not the provider

April 4, 2026Begin n Bounty

Begin n Bounty argues OAuth provider endpoints are saturated for hunters, and recommends focusing on the application implementation details like redirects and token exchange where real bugs tend to be found.

Most hunters attack the OAuth Provider (Google, Facebook). That's a dead end — millions have been there.
Hunt the Application side instead: how it sets up the flow, handles redirects, and exchanges tokens.
That's where real bugs live.
