The function reads a .pkl file and passes its contents to pickle.loads without validating the data source or content. If an application invokes algo_from_pickle on an attacker-supplied pickle file, an object defining __reduce__ is executed during deserialization, resulting in arbitrary code execution in the context of the application.","state":0,"publishedAt":"2026-09-27T01:28:41.003+00:00","modifiedAt":"2026-10-08T15:22:02.692+00:00","affected":[{"ecosystem":"Vendor product","name":"MONAI","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Project-MONAI\",\n                    \"product\": \"MONAI\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"1.5.2\"\n                        },\n                        {\n                            \"version\": \"1.5.2\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"packageURL\": \"pkg:pypi/monai\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:H/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":8.8,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:H","score":7.6,"severity":"HIGH"}],"references":["https://github.com/Project-MONAI/MONAI/security/advisories/GHSA-89gg-p5r5-q6r4","https://www.vulncheck.com/advisories/monai-before-1.5.2-remote-code-execution-via-pickle-deserialization"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100846","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100846","identifiers":["CVE-2026-100846"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
