CVE-2026-33731Public exploitNetwork attack vector

Wallet inflation via forged payment webhooks

Published Jul 16, 2026 · Updated Jul 16, 2026

Authorize.Net webhook bypass in World Wide Broadcast Network AVideo before 29.0 allows remote authenticated users to inflate wallets via forged requests. The handler accepts an invalid signature when transaction lookup succeeds, then prefers payload-supplied user and amount fields over gateway data. Exploitation requires a low-privileged account, an enabled Authorize.Net integration, and a valid small-purchase transaction ID; forged metadata can credit any wallet or activate premium access without matching payment.
