{"id":"CVE-2026-109361","summary":"MONAI 1.2.0 before 1.6.1 Insecure Deserialization RCE via nnUNetV2Runner postprocessing_file Path","details":"MONAI 1.2.0 before 1.6.1 contains an insecure deserialization vulnerability in nnUNetV2Runner that unpickles the postprocessing_file path read from inference_information.json without confining it to the results directory. Attackers who can modify inference_information.json can point it at a malicious pickle elsewhere on the filesystem to execute code when predict_ensemble_postprocessing runs.","aliases":["GHSA-8f32-8649-rv87"],"modified":"2026-10-13T02:46:57.102447798Z","published":"2026-10-12T16:05:40.286Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109361.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-502"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109361.json"},{"type":"FIX","url":"https://github.com/Project-MONAI/MONAI/commit/08576205c4de3c214976294d1dec8f7b2e78cdb9"},{"type":"ADVISORY","url":"https://github.com/Project-MONAI/MONAI/security/advisories/GHSA-8f32-8649-rv87"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-109361"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/monai-1.2.0-before-1.6.1-insecure-deserialization-rce-via-nnunetv2runner-postprocessing-file-path"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/project-monai/monai","events":[{"introduced":"c33f1ba588ee00229a309000e888f9817b4f1934"},{"fixed":"f2ec87ae9b536baaeca1d6bcc2b6349369e2af8f"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"1.2.0"},{"fixed":"1.6.1"}]}}],"versions":["1.6.0rc1","1.6.0","1.5.1","1.5.0","1.5.0rc1","1.4.1rc1","1.4.0","1.4.0rc12","1.4.0rc11","1.4.0rc10","1.4.0rc9","1.4.0rc8","1.4.0rc7","1.4.0rc6","1.4.0rc5","1.4.0rc4","1.4.0rc3","1.4.0rc2","1.4.0rc1","1.3.3rc1","1.3.1","1.3.1rc8","1.3.1rc7","1.3.1rc6","1.3.1rc5","1.3.1rc4","1.3.1rc3","1.3.1rc2","1.3.1rc1","1.3.0","1.3.0rc5","1.3.0rc4","1.3.0rc3","1.3.0rc2","1.3.0rc1","1.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-109361.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
