{"id":"CVE-2026-54653","summary":"`datamodel-code-generator` vulnerable to code injection in via attacker-controlled `default_factory` schema field","details":"datamodel-code-generator generates Pydantic v2 models, dataclasses, TypedDict, and msgspec.Struct from OpenAPI, JSON Schema, GraphQL, Avro, Protobuf, and raw JSON, YAML, or CSV. From  0.17.0 until 0.60.2, datamodel-code-generator preserves attacker-controlled default_factory values in src/datamodel_code_generator/parser/jsonschema.py through JsonSchemaObject.init and get_field_extras and emits them into Field(default_factory=...) or field(default_factory=...), allowing Python expression execution when the generated model is imported. This issue is fixed in version 0.60.2.","aliases":["GHSA-386q-5hp3-95m9"],"modified":"2026-08-01T03:33:02.883093416Z","published":"2026-07-28T21:48:04.619Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54653.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-1336","CWE-94"]},"references":[{"type":"WEB","url":"https://github.com/koxudaxi/datamodel-code-generator/releases/tag/0.60.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54653.json"},{"type":"ADVISORY","url":"https://github.com/koxudaxi/datamodel-code-generator/security/advisories/GHSA-386q-5hp3-95m9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54653"},{"type":"FIX","url":"https://github.com/koxudaxi/datamodel-code-generator/commit/17fc235e234cbcfaaadef8c74cb72c9687db0d1d"},{"type":"EVIDENCE","url":"https://gist.github.com/thegr1ffyn/9648b0fe4fcf7d569ac8e61dd11eebaf"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/koxudaxi/datamodel-code-generator","events":[{"introduced":"38f177135fefaeb02909eba9f0c9f4ef550f5a22"},{"fixed":"17fc235e234cbcfaaadef8c74cb72c9687db0d1d"},{"fixed":"e0ea4e45117acd41dcf6ae3a6639cc3f41b59045"}],"database_specific":{"extracted_events":[{"introduced":"0.17.0"},{"fixed":"0.60.2"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["0.60.1","0.60.0","0.59.1","0.59.0","0.58.0","0.57.0","0.56.1","0.56.0","0.55.0","0.54.1","0.54.0","0.53.0","0.52.2","0.52.1","0.52.0","0.51.0","0.50.0","0.49.0","0.48.0","0.47.0","0.46.0","0.45.0","0.44.0","0.43.1","0.43.0","0.42.2","0.42.1","0.42.0","0.41.0","0.40.0","0.39.0","0.38.0","0.37.0","0.36.0","0.35.0","0.34.0","0.33.0","0.32.0","0.31.2","0.31.1","0.31.0","0.30.2","0.30.1","0.30.0","0.29.0","0.28.5","0.28.4","0.28.3","0.28.2","0.28.1","0.28.0","0.27.3","0.27.2","0.27.1","0.27.0","0.26.5","0.26.4","0.26.3","0.26.2","0.26.1","0.26.0","0.25.9","0.25.8","0.25.7","0.25.6","0.25.5","0.25.4","0.25.3","0.25.2","0.25.1","0.25.0","0.24.2","0.24.1","0.24.0","0.23.0","0.22.1","0.22.0","0.21.5","0.21.4","0.21.3","0.21.2","0.21.1","0.21.0","0.20.0","0.19.0","0.18.1","0.18.0","0.17.2","0.17.1","0.17.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54653.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
