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.","state":0,"publishedAt":"2026-09-28T15:09:41.524+00:00","modifiedAt":"2026-09-30T14:43:10.011+00:00","affected":[{"ecosystem":"Vendor product","name":"unsloth-zoo","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"unslothai\",\n                    \"product\": \"unsloth-zoo\",\n                    \"packageURL\": \"pkg:github/unslothai/unsloth-zoo\",\n                    \"repo\": \"https://github.com/unslothai/unsloth-zoo\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2025.9.9\",\n                            \"versionType\": \"date\",\n                            \"lessThan\": \"2026.8.14\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"unsloth","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"unslothai\",\n                    \"product\": \"unsloth\",\n                    \"packageURL\": \"pkg:github/unslothai/unsloth\",\n                    \"repo\": \"https://github.com/unslothai/unsloth\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2025.9.9\",\n                            \"versionType\": \"date\",\n                            \"lessThan\": \"2026.8.20\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.6,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","score":8.1,"severity":"HIGH"}],"references":["https://github.com/unslothai/unsloth-zoo/pull/1083","https://github.com/unslothai/unsloth-zoo/pull/1108","https://github.com/unslothai/unsloth/commit/92ee0207a38ebc8af1a0e678aa92d7e7d901ea0d","https://www.vulncheck.com/advisories/unsloth-zoo-code-injection-via-model-type-in-config-json"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93348","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93348","identifiers":["CVE-2026-93348"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
