MONAI versions before 1.6.0 contain a remote code execution vulnerability in the algo_from_pickle() function due to unsafe pickle.loads()… (CVE-2026-100843)
MONAI versions before 1.6.0 have a remote code execution vulnerability in the algo_from_pickle() function caused by unsafe deserialization using pickle.loads(). This allows attackers to craft malicious pickle files that execute arbitrary system commands when processed by the vulnerable function.
AI Analysis
Technical Summary
The vulnerability in MONAI prior to version 1.6.0 is due to unsafe deserialization in the algo_from_pickle() function located in monai/auto3dseg/utils.py. The function uses pickle.loads() on attacker-controlled input, enabling remote code execution when malicious pickle files are deserialized. This is classified under CWE-502 (Deserialization of Untrusted Data). The CVSS 3.1 score is 7.8, indicating high severity with local attack vector, low attack complexity, no privileges required, user interaction required, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary system commands remotely on the affected system, potentially leading to full compromise of the host, data theft, or disruption of service.
Mitigation Recommendations
A fix is available in MONAI version 1.6.0 and later. Users should upgrade to version 1.6.0 or newer to remediate this vulnerability. No vendor advisory content was provided to indicate alternative mitigations or temporary fixes.
