Vercel launches $1M hacker challenge to test Sandbox security

Vercel is offering up to $1,000,000 in a public hacker challenge testing its Vercel Sandbox against escapes from the Firecracker microVM and bypasses of the host-side network boundary. Rewards reach $50,000 per report, administered through HackerOne (@Hacker0x01). The company says agents can now exploit vulnerable sandbox boundaries, so it is testing its own defenses in the open.
