A JSON integer there is dereferenced as a pointer.\n\nUntrusted JSON decoded with relaxed and dupkeys_as_arrayref can crash the process or dereference an address chosen by a JSON number.","state":0,"publishedAt":"2026-10-19T18:11:25.89+00:00","modifiedAt":"2026-10-19T18:11:25.89+00:00","affected":[{"ecosystem":"https://cpan.org/modules","name":"Cpanel-JSON-XS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"collectionURL\": \"https://cpan.org/modules\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"modules\": [\n                        \"Cpanel::JSON::XS\"\n                    ],\n                    \"packageName\": \"Cpanel-JSON-XS\",\n                    \"packageURL\": \"pkg:cpan/Cpanel-JSON-XS\",\n                    \"programFiles\": [\n                        \"XS.xs\"\n                    ],\n                    \"programRoutines\": [\n                        {\n                            \"name\": \"decode_hv\"\n                        }\n                    ],\n                    \"repo\": \"https://github.com/rurban/Cpanel-JSON-XS\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"4.80\",\n                            \"status\": \"affected\",\n                            \"version\": \"4.33\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/rurban/Cpanel-JSON-XS/commit/c52037857d6a99d96ebd1ce3e2fa769505f028cf.patch","https://metacpan.org/release/RURBAN/Cpanel-JSON-XS-4.80/changes","https://www.cve.org/CVERecord?id=CVE-2026-9334"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-110674","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-110674","identifiers":["CVE-2026-110674"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
