{"id":"CVE-2026-31218","details":"The _load_model() function in the neural_magic_training.py script of the optimate project in commit a6d302f912b481c94370811af6b11402f51d377f (2024-07-21) is vulnerable to insecure deserialization (CWE-502). When loading a model state dictionary from a state_dict.pt file via torch.load(), the function does not enable the weights_only=True security parameter. This allows the deserialization of arbitrary Python objects through the Pickle module. A remote attacker can exploit this by providing a maliciously crafted state_dict.pt file within a directory specified via the --model argument, leading to arbitrary code execution during the deserialization process on the victim's system.","modified":"2026-10-28T02:30:42.664766975Z","published":"2026-05-12T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31218.json"},"references":[{"type":"WEB","url":"https://www.notion.so/CVE-2026-31218-35d1e139318881839bc8cf6007be2c76"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31218.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31218"},{"type":"PACKAGE","url":"https://github.com/nebuly-ai/optimate"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nebuly-ai/optimate","events":[{"introduced":"0"},{"last_affected":"a6d302f912b481c94370811af6b11402f51d377f"}],"database_specific":{"extracted_events":[{"source":"DESCRIPTION","range":[{"introduced":"0"},{"last_affected":"a6d302f912b481c94370811af6b11402f51d377f"}]}]}}],"versions":["chatllama0.0.4","chatllama0.0.3","v0.9.0","v0.8.1","v0.8.0","v0.7.3","v0.7.2","v0.7.1","v0.7.0","v0.6.0","v0.5.0","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.2","v0.3.1","v0.3.0","v0.2.2","v0.2.1","v0.2.0","v0.1.2","v0.1.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-31218.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
