When any key in a hash is UTF-8 flagged, every key is decoded as UTF-8 for the comparison, including byte-string keys that the encoder writes out as Latin-1 characters. A byte-string key whose bytes are valid UTF-8 is sorted out of order, and two keys that encode differently can compare equal and are left in hash order.\n\nThe same data can encode to different canonical documents across processes.","categories":["Applications & CMS"],"product":"","vendor":"","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-110687","source_modified_at":"2026-10-19T18:12:22.028Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":null,"vendor":null,"versions":[{"lessThan":"4.80","status":"affected","version":"4.43","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-110687","source_modified_at":"2026-10-19T18:12:22.028Z","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":0.06175,"score_date":"2026-10-23"},"published_at":"2026-10-19T18:12:22.028Z","modified_at":"2026-10-19T18:12:22.028Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-110687","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T18:12:22.028Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-110687","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/bb9da30b67f637f4d57922f0e043376363f28f0c.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":"2026-10-19T18:12:22.028Z","content_hash":"9ed657fe9faea76b2726b2a7132fb705123bf94017c8001b43385a26ccc7c480"}}
