An extra reference is never released, so the array and every value in it outlive the decoded structure. The array also leaks when decoding fails after a duplicate key.\n\nRepeatedly decoding untrusted JSON with a duplicate key holding a large value exhausts process memory.","categories":["Applications & CMS"],"product":"","vendor":"","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-110677","source_modified_at":"2026-10-19T18:11:53.004Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":null,"vendor":null,"versions":[{"lessThan":"4.80","status":"affected","version":"4.28","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-110677","source_modified_at":"2026-10-19T18:11:53.004Z","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":0.00171,"percentile":0.06177,"score_date":"2026-10-23"},"published_at":"2026-10-19T18:11:53.004Z","modified_at":"2026-10-19T18:11:53.004Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-110677","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T18:11:53.004Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-110677","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/edb13030a708afc2cde0d2629fb6bdd31288ce6c.patch","tags":["patch"]},{"source":"CVE List","url":"https://metacpan.org/release/RURBAN/Cpanel-JSON-XS-4.80/changes","tags":["release-notes"]}],"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":"2026-10-19T18:11:53.004Z","content_hash":"68a3cc2bc1db00c3c8939ddb8026d2fefbfa76cb5f2a8ad903e239e0c87a35b9"}}
