{"identifier":"CVE-2026-78497","cve":{"id":"CVE-2026-78497","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":"2026-10-18T12:17:15.350000+00:00","modified":"2026-10-20T19:18:15.957000+00:00","status":"Awaiting Analysis","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","cvss_version":"3.1","affected":[],"weaknesses":["CWE-95"],"references":[{"url":"https://github.com/kawamurashingo/JQ-Lite/commit/c461721ae3d5a90d6d94dbb234c1b8dfee5c1769.patch","source":"9b29abf9-4ab0-4765-b253-1875cd9b441e"},{"url":"https://metacpan.org/release/SHINGO/JQ-Lite-2.51/changes","source":"9b29abf9-4ab0-4765-b253-1875cd9b441e"},{"url":"http://www.openwall.com/lists/oss-security/2026/10/18/3","source":"af854a3a-2127-422b-91ae-364da2661108"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":8.4,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.5,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-20T18:22:07.986736Z","id":"CVE-2026-78497","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:23:16.500471+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00196,"percentile":0.09346,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/kawamurashingo/JQ-Lite/commit/c461721ae3d5a90d6d94dbb234c1b8dfee5c1769.patch","investigate_url":"https://investigate.aeglixmind.com/#github.com"},{"domain":"metacpan.org","source_url":"https://metacpan.org/release/SHINGO/JQ-Lite-2.51/changes","investigate_url":"https://investigate.aeglixmind.com/#metacpan.org"},{"domain":"www.openwall.com","source_url":"http://www.openwall.com/lists/oss-security/2026/10/18/3","investigate_url":"https://investigate.aeglixmind.com/#www.openwall.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-78497","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-78497","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-78497","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
