Malicious pickle files embedding ensurepip._run_pip calls in __reduce__ methods bypass picklescan detection and achieve remote code execution upon pickle.load() invocation.","published":"2026-06-22T21:04:41.975Z","modified":"2026-08-07T11:50:25.307100417Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"picklescan","fixedVersion":"0.0.30"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71344.json"},{"type":"ADVISORY","url":"https://github.com/mmaitre314/picklescan/security/advisories/GHSA-xp4f-hrf8-rxw7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71344"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/picklescan-arbitrary-code-execution-via-undetected-ensurepip-run-pip-function"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:25.307100417Z"}}
