Attackers can embed a newline in a nested model_type value within a malicious model's config.json to terminate the generated import statement and execute arbitrary Python code via exec() in unsloth_compile_transformers(), achieving remote code execution as the loading user when the model is loaded for training or inference.","published":"2026-09-28T16:17:17.643","modified":"2026-09-28T16:17:17.643","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/unslothai/unsloth-zoo/pull/1083","label":"unslothai/unsloth-zoo#1083"},"references":[{"type":"WEB","url":"https://github.com/unslothai/unsloth-zoo/pull/1083"},{"type":"WEB","url":"https://github.com/unslothai/unsloth-zoo/pull/1108"},{"type":"WEB","url":"https://github.com/unslothai/unsloth/commit/92ee0207a38ebc8af1a0e678aa92d7e7d901ea0d"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/unsloth-zoo-code-injection-via-model-type-in-config-json"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-28T16:17:17.643"}}
