When an authenticated administrator submits a value containing shell metacharacters, the application constructs nftables/iptables rule strings using fmt.Sprintf and executes them via bash -c as root. Because the listen field lacks port or format validation, arbitrary OS commands can be injected and executed with root privileges.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":50,"depthScoreParts":{"impact":50.1,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[{"seq":217807,"id":"CVE-2026-107202","ts":1791410348397,"field":"cvss","old":null,"new":"9.1"},{"seq":217806,"id":"CVE-2026-107202","ts":1791410348397,"field":"severity","old":"none","new":"critical"}]}
