CVE-2026-22819Public exploitNetwork attack vector

Subscription quota bypass via unlocked subdomain insert

Published Jan 14, 2026 · Updated Jan 14, 2026

Race condition in OutRay before 0.1.5 allows remote authenticated users to exceed their organization's subdomain quota via parallel requests. The subdomain API reads the plan limit and existing row count, then inserts a new row without transaction locking, so concurrent requests act on the same stale count. A valid account and overlapping requests are required; successful exploitation creates persistent subdomains beyond the subscribed limit.
