Only the syntax and order of the ranges are checked, so row=1-400000000 on a two-line file allocates 400 million elements.\n\nAn application that passes a request-supplied fragment to fragment or csv can be made to exhaust memory, which ends the process with an Out of memory error that eval cannot catch.","published":"2026-10-16T23:17:00.000Z","lastModified":"2026-10-20T19:17:29.000Z","status":"Awaiting Analysis","sourceIdentifier":"9b29abf9-4ab0-4765-b253-1875cd9b441e","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-770"],"affected":[],"epss":{"score":0.00408,"percentile":0.34844,"date":"2026-10-26","history":[{"date":"2026-10-17","score":0.00192,"percentile":0.08249}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.41%).
