OAuth Client ID Spoofing: Why Fake Client IDs Are Gaining Traction for Stealthy Enumeration
AI-collected research leads through 22 September 2026, including targeted additions between broader sweeps. Unranked, incomplete, not community-vetted, and subject to change.
Compares OAuth password-grant responses for registered, unregistered, random and malformed client IDs. The error matrix distinguishes user and credential validation from successful token issuance and explains why missing application names complicate sign-in monitoring. Validating a password this way does not establish an authenticated session or a Conditional Access bypass.
