{"cve":"CVE-2026-45770","nvd":{"published":"2026-09-10T22:16:57.117","modified":"2026-09-16T18:28:14.913","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-693","CWE-787"],"references":["https://forum.suricata.io/t/suricata-8-0-5-and-7-0-16-released/6315","https://github.com/OISF/suricata/security/advisories/GHSA-653j-cc95-vj4c","https://redmine.openinfosecfoundation.org/issues/8556"],"products":["oisf:suricata"],"source":"nvd","synced_at":"2026-10-19T22:52:53.108888569+00:00"},"epss":{"cve":"CVE-2026-45770","score":0.0048,"percentile":0.41445,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
