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." } ], "tags": [ "x_open-source" ], "datePublic": "2026-08-23T00:00:00.000Z", "problemTypes": [ { "descriptions": [ { "lang": "en", "cweId": "CWE-94", "description": "Improper Control of Generation of Code ('Code Injection')", "type": "CWE" } ] } ], "affected": [ { "defaultStatus": "unaffected", "vendor": "unslothai", "product": "unsloth-zoo", "packageURL": "pkg:github/unslothai/unsloth-zoo", "repo": "https://github.com/unslothai/unsloth-zoo", "versions": [ { "status": "affected", "version": "2025.9.9", "versionType": "date", "lessThan": "2026.8.14" } ] }, { "defaultStatus": "unaffected", "vendor": "unslothai", "product": "unsloth", "packageURL": "pkg:github/unslothai/unsloth", "repo": "https://github.com/unslothai/unsloth", "versions": [ { "status": "affected", "version": "2025.9.9", "versionType": "date", "lessThan": "2026.8.20" } ] } ], "metrics": [ { "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ], "cvssV4_0": { "attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "NONE", "privilegesRequired": "NONE", "userInteraction": "PASSIVE", "vulnConfidentialityImpact": "HIGH", "subConfidentialityImpact": "NONE", "vulnIntegrityImpact": "HIGH", "subIntegrityImpact": "NONE", "vulnAvailabilityImpact": "NONE", "subAvailabilityImpact": "NONE", "exploitMaturity": "NOT_DEFINED", "Safety": "NOT_DEFINED", "Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "valueDensity": "NOT_DEFINED", "vulnerabilityResponseEffort": "NOT_DEFINED", "providerUrgency": "NOT_DEFINED", "version": "4.0", "baseSeverity": "HIGH", "baseScore": 8.6, "vectorString": "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" } }, { "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ], "cvssV3_1": { "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "REQUIRED", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "NONE", "version": "3.1", "baseSeverity": "HIGH", "baseScore": 8.1, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N" } } ], "references": [ { "url": "https://github.com/unslothai/unsloth-zoo/pull/1083", "name": "Pull Request (1)", "tags": [ "patch", "issue-tracking" ] }, { "url": "https://github.com/unslothai/unsloth-zoo/pull/1108", "name": "Pull Request (2)", "tags": [ "patch", "issue-tracking" ] }, { "url": "https://github.com/unslothai/unsloth/commit/92ee0207a38ebc8af1a0e678aa92d7e7d901ea0d", "name": "Unsloth Zoo Dependency Bump", "tags": [ "patch" ] }, { "url": "https://www.vulncheck.com/advisories/unsloth-zoo-code-injection-via-model-type-in-config-json", "tags": [ "third-party-advisory" ] } ], "credits": [ { "lang": "en", "value": "Ariel Fogel (afogel) of Pillar Security", "type": "finder" } ], "source": { "discovery": "UNKNOWN" }, "x_generator": { "engine": "vulncheck" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-09-30T14:42:53.294398Z", "id": "CVE-2026-93348", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-09-30T14:43:10.011Z" } } ] } }
