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.","categories":["Applications & CMS"],"product":"","vendor":"","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-110674","source_modified_at":"2026-10-19T18:11:25.890Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":null,"vendor":null,"versions":[{"lessThan":"4.80","status":"affected","version":"4.33","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-110674","source_modified_at":"2026-10-19T18:11:25.890Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":null,"ecosystem":null},"version":"4.80","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00199,"percentile":0.09263,"score_date":"2026-10-23"},"published_at":"2026-10-19T18:11:25.890Z","modified_at":"2026-10-19T18:11:25.890Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-110674","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T18:11:25.890Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-110674","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/rurban/Cpanel-JSON-XS/commit/c52037857d6a99d96ebd1ce3e2fa769505f028cf.patch","tags":["patch"]},{"source":"CVE List","url":"https://metacpan.org/release/RURBAN/Cpanel-JSON-XS-4.80/changes","tags":["release-notes"]},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-9334","tags":["related"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"summary-specific-product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T18:11:25.890Z","content_hash":"7d9f688664ff230ac5d96d04844428e795ca9a4d6c1396bf317e9f7e4c17230c"}}
