Description
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.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Fix
Upgrade the affected component to the fixed release for CVE-2026-47216, or apply your distribution's backported patch — distro builds are often patched at an older version number, so check your vendor's advisory rather than the upstream version alone.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
