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.","cvssScore":7.6,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:H","cwes":["CWE-502"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Project-MONAI/MONAI/security/advisories/GHSA-89gg-p5r5-q6r4","tags":[]},{"url":"https://www.vulncheck.com/advisories/monai-before-1.5.2-remote-code-execution-via-pickle-deserialization","tags":[]}],"exploitRefs":[{"url":"https://github.com/Project-MONAI/MONAI/security/advisories/GHSA-89gg-p5r5-q6r4","tags":[]}],"hasPoc":true,"ai":null}
