CVE-2026-47216Network attack vector

Unauthenticated server crash via unhandled multi-search exception

Published Jun 12, 2026 · Updated Jun 12, 2026

Denial of service in the /multi_search endpoint in Typesense before 29.1 and 30.0 through 30.1 allows remote attackers to crash the server. Request processing leaves a crafted-input exception unhandled, terminating the server process, but published material does not identify the malformed field or failing code path. No authentication or user interaction is required, and a successful request interrupts search service until the process is restarted; confidentiality and integrity remain unaffected.
