The script calls torch.load() with weights_only=False on user-supplied .pt files, allowing attackers to execute arbitrary code if a maliciously crafted model file is loaded. An attacker can exploit this by convincing a victim to download and place a malicious model file in a local directory with a specific filename pattern. This vulnerability may lead to arbitrary code execution with the privileges of the user running the script."}]}, "problemtype": {"problemtype_data": [{"description": []}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2025-50461", "ASSIGNER": "cve@mitre.org"}}, "impact": {}, "publishedDate": "2025-08-19T14:15Z", "configurations": {"nodes": [], "CVE_data_version": "4.0"}, "lastModifiedDate": "2025-08-19T20:15Z"}
