AnalysisAIv1 – Mar 12, 2026

Outray versions prior to 0.1.5 lack database transaction locking in the subdomain creation API endpoint, allowing authenticated users to bypass rate limits and provision more subdomains than permitted by their service tier. Public exploit code exists for this vulnerability, which affects the quota enforcement mechanism for free plan users. Upgrade to version 0.1.5 or later to remediate.
