CVE-2026-45770
CVE-2026-45770 updated by NVD
Summary
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Starting in version 8.0.0 and prior to version 8.0.5, a Lua rule that registers too many flow variables can corrupt Lua detection state and may bypass Suricata's restricted Lua sandbox. This requires an affected Lua script/rule to be loaded. Excessive flow variables being registered may also cause Suricata to crash. Version 8.0.5 contains a fix. As a workaround, disable `security.lua.allow-rules` unless Lua rules are required.
