High CVSS 7.5
CVE-2026-74244
Redhat Openshift Update Service
A flaw was found in Red Hat Quay's Stripe billing webhook handler. This vulnerability allows an unauthenticated attacker to forge billing events by sending crafted JSON requests to the `/webhooks/stripe` endpoint without validating the Stripe-Signature header. 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.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can modify or destroy data.
- Weakness
- A cryptographic signature is not properly verified, so forged content passes as authentic.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
