{"id":"CVE-2026-78497","summary":"JQ::Lite versions before 2.51 for Perl execute Perl code embedded in a query's regular expression by compiling it with string eval","details":"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.","modified":"2026-10-21T03:00:00.128287705Z","published":"2026-10-18T11:32:05.853Z","database_specific":{"cna_assigner":"CPANSec","cwe_ids":["CWE-95"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/78xxx/CVE-2026-78497.json"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/10/18/3"},{"type":"WEB","url":"https://cpan.org/modules"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/78xxx/CVE-2026-78497.json"},{"type":"PACKAGE","url":"https://github.com/kawamurashingo/JQ-Lite"},{"type":"FIX","url":"https://github.com/kawamurashingo/JQ-Lite/commit/c461721ae3d5a90d6d94dbb234c1b8dfee5c1769.patch"},{"type":"ADVISORY","url":"https://metacpan.org/release/SHINGO/JQ-Lite-2.51/changes"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-78497"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kawamurashingo/jq-lite","events":[{"introduced":"0"},{"fixed":"4bf98b0e2e2d6fa5317a63fae4f6ef82fd8a5f8c"},{"fixed":"c461721ae3d5a90d6d94dbb234c1b8dfee5c1769"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"2.51"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"},{"range":[{"fixed":"c461721ae3d5a90d6d94dbb234c1b8dfee5c1769"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["v2.50","v2.49","v2.48","2.47","2.46","v2.44","v2.43","v2.42","v2.39","v2.29","v2.21","v2.14","v2.10","v1.98","v1.79","v1.78","v1.76","v1.75","v1.73","v1.72","v1.71"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-78497.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
