{"id":"CVE-2026-78497","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-78497","generatedAt":"2026-10-28T04:46:48.470Z","title":"JQ::Lite versions before 2.51 for Perl execute Perl code embedded in a query's regular expression by compiling it with string eval.","description":"JQ::Lite versions before 2.51 for Perl execute Perl code embedded in a query's regular expression by compiling it with string eval.\n\nThe pattern given to test(), match(), or the match and =~ conditions of select() is placed in a `qr'...'` literal and compiled as source text, so a `(?{ ... })` code block in it runs without `use re 'eval'`. Single quotes in the pattern are escaped, but a code block runs in place and needs none.\n\nAn attacker who supplies a query, or text that an application inserts into the pattern of one, can execute arbitrary Perl code in the calling process.","published":"2026-10-18T12:17:15.000Z","lastModified":"2026-10-20T19:18:16.000Z","status":"Awaiting Analysis","sourceIdentifier":"9b29abf9-4ab0-4765-b253-1875cd9b441e","cvss":{"version":"3.1","score":8.4,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-95"],"affected":[],"epss":{"score":0.00196,"percentile":0.0925,"date":"2026-10-27","history":[{"date":"2026-10-19","score":0.00169,"percentile":0.05932}]},"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 (0.20%).
