{"cve":"CVE-2025-61622","nvd":{"published":"2025-10-01T10:15:34.080","modified":"2026-10-09T09:10:00.213","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-502"],"references":["https://lists.apache.org/thread/vfn9hp9qt06db5yo1gmj3l114o3o2csd","http://www.openwall.com/lists/oss-security/2025/09/29/3"],"products":["apache:fory"],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2025-61622","score":0.45125,"percentile":0.98773,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-538v-3wq9-4h3r","url":"https://osv.dev/vulnerability/GHSA-538v-3wq9-4h3r","summary":"Apache Pyfory python is vulnerable to deserialization of untrusted data","modified":"2026-06-29T12:26:52.243778954Z","packages":[{"ecosystem":"PyPI","name":"pyfory","purl":"pkg:pypi/pyfory","ranges":[">=0.12.0 <0.12.3"],"fixed":["0.12.3"]},{"ecosystem":"PyPI","name":"pyfury","purl":"pkg:pypi/pyfury","ranges":[">=0.1.0 <=0.10.3"],"fixed":[]}]},{"id":"PYSEC-2026-490","url":"https://osv.dev/vulnerability/PYSEC-2026-490","summary":"Apache Pyfory python is vulnerable to deserialization of untrusted data","modified":"2026-07-01T20:23:02.648327Z","packages":[{"ecosystem":"PyPI","name":"pyfory","purl":"pkg:pypi/pyfory","ranges":[">=0.12.0 <0.12.3"],"fixed":["0.12.3"]}]},{"id":"PYSEC-2026-491","url":"https://osv.dev/vulnerability/PYSEC-2026-491","summary":"Apache Pyfory python is vulnerable to deserialization of untrusted data","modified":"2026-07-01T20:23:02.702735Z","packages":[{"ecosystem":"PyPI","name":"pyfury","purl":"pkg:pypi/pyfury","ranges":[">=0.1.0 <=0.10.3"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
