From version 0.38.0 through 0.70.5, BaseGenerator.parse_fixed interpolates a fixed type's aliases value directly into a generated types.confixed annotation. A list is represented with quoted entries, but a bare string is emitted as an unquoted Python expression and evaluated when the generated module is imported, allowing arbitrary code execution from a crafted schema. Version 0.70.6 fixes the vulnerability by rejecting aliases values that are not lists.","state":0,"publishedAt":"2026-10-13T17:53:48.228+00:00","modifiedAt":"2026-10-13T20:21:19.992+00:00","affected":[{"ecosystem":"Vendor product","name":"dataclasses-avroschema","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"marcosschroh\",\n                    \"product\": \"dataclasses-avroschema\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.38.0, < 0.70.6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/marcosschroh/dataclasses-avroschema/security/advisories/GHSA-8j5c-xq6f-2c43","https://github.com/marcosschroh/dataclasses-avroschema/commit/429f3d705d2d04c0c65e2ef832daed5ff91318fc","https://github.com/marcosschroh/dataclasses-avroschema/releases/tag/0.70.6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-108384","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-108384","identifiers":["CVE-2026-108384"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
