High severity, CVSS 7.5. EPSS: 0.2% chance of exploitation in the next 30 days.
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.
