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."}],"source":{"advisory":"GHSA-653j-cc95-vj4c","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-11T14:36:27.298514Z","id":"CVE-2026-45770","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-11T14:37:32.339Z"}}]}}
