{"id":"CVE-2026-53875","summary":"picklescan - Scanning Bypass via Dynamic Eval in scan_pytorch","details":"picklescan before 1.0.3 contains a scanning bypass vulnerability in the scan_pytorch function that allows attackers to embed malicious magic numbers via dynamic eval using the __reduce__ trick. Attackers can craft malicious PyTorch payloads that evade picklescan detection while remaining executable, enabling arbitrary code execution when loaded with torch.load().","aliases":["GHSA-97f8-7cmv-76j2"],"modified":"2026-07-08T08:11:31.437273532Z","published":"2026-06-17T15:05:04.255Z","database_specific":{"cwe_ids":["CWE-95"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53875.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53875.json"},{"type":"ADVISORY","url":"https://github.com/mmaitre314/picklescan/security/advisories/GHSA-97f8-7cmv-76j2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53875"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/picklescan-scanning-bypass-via-dynamic-eval-in-scan-pytorch"},{"type":"FIX","url":"https://github.com/mmaitre314/picklescan/commit/134179474539648ba7dee1317959529fbd0e7f89"},{"type":"FIX","url":"https://github.com/mmaitre314/picklescan/commit/2a8383cfeb4158567f9770d86597300c9e508d0f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mmaitre314/picklescan","events":[{"introduced":"0"},{"fixed":"b9997634683a4f4bd0c7e3701e7ce7e90fe70e8c"},{"fixed":"2a8383cfeb4158567f9770d86597300c9e508d0f"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.0.3"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v1.0.2","v1.0.1","v1.0.0","v0.0.35","v0.0.34","v0.0.33","v0.0.32","v0.0.31","v0.0.30","v0.0.29","v0.0.28","v0.0.27","v0.0.26","v0.0.25","v0.0.24","v0.0.23","v0.0.22","v0.0.21","v0.0.20","v0.0.19","v0.0.18","v0.0.17","v0.0.15","v0.0.14","v0.0.13","v0.0.12","v0.0.11","v0.0.10","v0.0.9","v0.0.8","v0.0.7","v0.0.6","v0.0.5","v0.0.4","v0.0.3","v0.0.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53875.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
