{"schemaVersion":3,"id":"CVE-2026-64608","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Heap type confusion and out-of-bounds read/write in the Apache Fory C++ implementation. When deserializing data in compatible mode, the field-skip paths do not correctly validate the declared field types against the actual data, so input with an inconsistent schema can cause type confusion and out-of-bounds memory access. Only the C++ implementation is affected; other language implementations of Apache Fory are not.\n\nThis issue affects Apache Fory C++: from 0.14.0 before 1.4.0.\n\nUsers are recommended to upgrade to version 1.4.0, which fixes the issue.","dates":{"published":"2026-07-21T09:34:12.817Z","modified":"2026-07-21T18:28:16.365Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":9.8,"severity":"critical","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":9.8,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":9.8,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00806,"percentile":0.55982,"severity":"low","asOf":"2026-10-18T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-18T00:00:00.000Z","baselineScore":0.00806},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00806,"percentile":0.55982}],"last30":[{"date":"2026-09-18T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00806,"percentile":null},{"date":"2026-10-10T00:00:00.000Z"
