CVE-2025-30350Public exploitNetwork attack vector

Asset denial via unconsumed S3 HEAD streams

Published Mar 26, 2025 · Updated Mar 26, 2025

Resource exhaustion in Directus allows remote attackers to interrupt S3-backed asset access by sending bursts of HEAD requests. The S3 storage driver's HEAD path obtains object streams without consuming them, leaving NodeHttpHandler Agent sockets occupied until its pool is exhausted. The public asset route requires no authentication, but the condition requires S3-backed storage and sustained parallel requests; all asset policies then receive HTTP 403 responses.
