Summary

Typesense is a fast, typo-tolerant search engine. Prior to versions 29.1 and 30.2, there is an unauthenticated denial-of-service vulnerability in the /multi_search endpoint. A specially crafted request can trigger an unhandled exception during request processing, causing the server process to terminate. This issue can be exploited over the network without authentication and results in service unavailability. The duration of impact may vary depending on system configuration and dataset size. This issue has been patched in versions 29.1 and 30.2.
