This critical-severity CVE scores 9.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 84% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, the cloneTo() Livewire action in ResourceOperations.php authorizes the source resource but resolves destination resources with unscoped Eloquent lookups, allowing an authenticated user to clone resources into destinations owned by other teams and access cross-tenant resources. This issue is fixed in version 4.0.0-beta.464.
