{"id":"CVE-2025-61622","details":"Deserialization of untrusted data in python in pyfory versions 0.12.0 through 0.12.2, or the legacy pyfury versions from 0.1.0 through 0.10.3: allows arbitrary code execution. An application is vulnerable if it reads pyfory serialized data from untrusted sources. An attacker can craft a data stream that selects pickle-fallback serializer during deserialization, leading to the execution of `pickle.loads`, which is vulnerable to remote code execution.\n\nUsers are recommended to upgrade to pyfory version 0.12.3 or later, which has removed pickle fallback serializer and thus fixes this issue.","aliases":["GHSA-538v-3wq9-4h3r"],"modified":"2026-04-10T05:33:49.583860Z","published":"2025-10-01T10:15:34.080Z","references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2025/09/29/3"},{"type":"REPORT","url":"https://lists.apache.org/thread/vfn9hp9qt06db5yo1gmj3l114o3o2csd"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/fory","events":[{"introduced":"d59c458dce25f0c0c363104c1d07a3533cdfb00a"},{"last_affected":"a48e9032dfbcc6020883d9eba072647626ff4975"},{"introduced":"7e6db1e97811b1cc95c9b8f5088e2abebe7f299a"},{"last_affected":"2e3dc3a432dffe6e1715b8d26f7d10ebc14bbbb6"}],"database_specific":{"versions":[{"introduced":"0.1.0"},{"last_affected":"0.10.3"},{"introduced":"0.12.0"},{"last_affected":"0.12.2"}]}}],"versions":["v0.12.0","v0.12.0-rc1","v0.12.1","v0.12.1-rc1","v0.12.2","v0.12.2-rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-61622.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
