{"schema":"threatline.record/2","record":{"id":"CVE-2026-108384","aliases":["GHSA-8j5c-xq6f-2c43"],"summary":"dataclasses-avroschema allows code injection through fixed-type aliases supplied as a bare string","details":"dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. 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.","categories":["Unclassified"],"product":"dataclasses-avroschema","vendor":"marcosschroh","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-108384","source_modified_at":"2026-10-13T20:21:19.992Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"dataclasses-avroschema","vendor":"marcosschroh","versions":[{"version":">= 0.38.0, < 0.70.6","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00343,"percentile":0.26592,"score_date":"2026-10-23"},"published_at":"2026-10-13T17:53:48.228Z","modified_at":"2026-10-13T20:21:19.992Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-108384","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T20:21:19.992Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-108384","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/marcosschroh/dataclasses-avroschema/security/advisories/GHSA-8j5c-xq6f-2c43","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/marcosschroh/dataclasses-avroschema/commit/429f3d705d2d04c0c65e2ef832daed5ff91318fc","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/marcosschroh/dataclasses-avroschema/releases/tag/0.70.6","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-13T20:14:08.820272Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-13T20:21:19.992Z","content_hash":"4c4a2d0354a696c2831947fc5208e226524b7f22d0de32d45019dd9ecc886e18"}}
