Any authenticated user permitted to upload PCAP/log files can upload a small, highly compressible file (e.g. a gzip bomb) that decompresses to an effectively unbounded size on disk, exhausting the shared Docker volume used by OpenSearch, Logstash, Arkime, and Zeek, and disrupting the platform for all users.","published":"2026-10-08T18:17:20.000Z","lastModified":"2026-10-13T17:17:17.000Z","status":"Awaiting Analysis","sourceIdentifier":"ics-cert@hq.dhs.gov","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-409"],"affected":[],"epss":{"score":0.00456,"percentile":0.39351,"date":"2026-10-26","history":[{"date":"2026-10-09","score":0.00371,"percentile":0.28965}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.46%).
