From version 0.47.3 through 0.70.5, FieldRepresentation.get_field_default inserts a schema-controlled referenced record name into the callable position of a generated default_factory lambda without validating it as an Avro name. A crafted record name can become an arbitrary Python expression that executes when an instance of the generated model consumes the field default. Version 0.70.6 fixes the vulnerability by rejecting record names that do not match the Avro name grammar.","state":0,"publishedAt":"2026-10-13T17:17:07.502+00:00","modifiedAt":"2026-10-16T22:23:01.639+00:00","affected":[{"ecosystem":"Vendor product","name":"dataclasses-avroschema","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"marcosschroh\",\n                    \"product\": \"dataclasses-avroschema\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.47.3, < 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-jcjg-gjg5-xp7v","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-2026-108376","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-108376","identifiers":["CVE-2026-108376"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
