CVE-2026-61484Network attack vector

Unauthenticated code execution via Storable deserialization

Published Aug 5, 2026 · Updated Aug 5, 2026

Deserialization in Apache Lucy all versions allows remote attackers to execute code or crash SearchServer through crafted RPC data. LucyX::Remote::SearchServer passes an unauthenticated network request body to Perl Storable::thaw without validating the serialized object graph. Exposure requires the optional remote search server to be running and reachable; local-only library use lacks the network entry point.
