Inside the Vercel Breach: Highlighting OAuth Token Risk

In a special edition of Cybersecurity Today, host Jim Love and guest Jamie Blasco (CTO, Nudge Security) discuss Vercel, a major developer hosting platform, and a breach tied to OAuth grants and shadow AI. Reporting shared by Contrast Security's David Lindner describes how a Context AI employee downloaded Roblox AutoFarm scripts, got infected with an info stealer, and attackers harvested credentials, compromised Context AI, then used an over-permissioned OAuth token from a Vercel employee who had signed up to Context AI with an enterprise account and clicked "allow all," with Vercel working with Mandiant on a breach allegedly being sold for $2 million. The episode emphasizes that MFA may not mitigate OAuth abuse, urges admin-managed consent, continuous inventory and auditing of OAuth grants, and better visibility into risky third-party app access across Google Workspace and Microsoft 365.
