Medium5.9CVE-2026-74244 · Published Aug 14, 2026 · updated Aug 20, 2026
A flaw was found in Red Hat Quay's Stripe billing webhook handler.

Successful exploitation can lead to the unauthorized resetting of a namespace's build quota to its maximum and trigger unsolicited billing emails to namespace administrators.
