The vulnerabilities impact Suricata versions prior to 8.0.5 and 7.0.16. Successful exploitation of these vulnerabilities could lead to remote code execution (RCE) and denial-of-service (DoS) conditions. The advisory identifies CVE-2026-45747, CVE-2026-45751, CVE-2026-45752, CVE-2026-45759, CVE-2026-45761, CVE-2026-45762, CVE-2026-45763, CVE-2026-45764, CVE-2026-45765, CVE-2026-45766, CVE-2026-45767, CVE-2026-45768, CVE-2026-45769, CVE-2026-45770, CVE-2026-46352, and CVE-2026-46387. Due to the nature of network threat detection engines, exploitation could severely impact network security monitoring capabilities.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003cp\u003eGiven the nature of Suricata as a network analysis tool, the attack chain depends on the specific vulnerability being exploited, but the general steps would involve:\u003c/p\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker crafts a malicious network packet or series of packets.\u003c/li\u003e\n\u003cli\u003eThe attacker sends the malicious traffic to a network segment monitored by a vulnerable Suricata instance.\u003c/li\u003e\n\u003cli\u003eSuricata processes the malicious traffic.\u003c/li\u003e\n\u003cli\u003eA vulnerability in the Suricata parsing or processing logic is triggered by the crafted packet.

An attacker could potentially execute arbitrary code on the Suricata sensor, enabling lateral movement or data exfiltration. A successful denial-of-service attack could blind security teams to malicious activity on the network. The specific impact depends on the organization\u0026rsquo;s reliance on Suricata for network security.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eImmediately upgrade Suricata to version 8.0.5 or 7.0.16 or later to patch the vulnerabilities described in the advisory.\u003c/li\u003e\n\u003cli\u003eMonitor network traffic for patterns associated with known Suricata exploits.\u003c/li\u003e\n\u003cli\u003eImplement network segmentation to limit the potential impact of a compromised Suricata instance.\u003c/li\u003e\n\u003cli\u003eDeploy the Sigma rules below to your SIEM to detect potential exploitation attempts of CVE-2026-45747, CVE-2026-45751, CVE-2026-45752, CVE-2026-45759, CVE-2026-45761, CVE-2026-45762, CVE-2026-45763, CVE-2026-45764, CVE-2026-45765, CVE-2026-45766, CVE-2026-45767, CVE-2026-45768, CVE-2026-45769, CVE-2026-45770, CVE-2026-46352, and CVE-2026-46387.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-05-20T14:09:04Z","date_published":"2026-05-20T14:09:04Z","id":"https://feed.craftedsignal.io/briefs/2026-05-suricata-multiple-vulns/","summary":"Multiple vulnerabilities in Suricata versions before 8.0.5 and 7.0.16 could allow a remote attacker to execute arbitrary code or cause a denial-of-service condition.","title":"Multiple Vulnerabilities in Suricata Network Threat Detection Engine","url":"https://feed.craftedsignal.io/briefs/2026-05-suricata-multiple-vulns/"}],"language":"en","title":"CraftedSignal Threat Feed — Suricata","version":"https://jsonfeed.org/version/1.1"}
