CVE-2026-108375

HighCVSS 8.8
Published: Translated: NVD NIST

Summary

dataclasses-avroschema versions 0.38.0 through 0.70.5 insert schema-controlled string, UUID, bytes, and fixed field defaults into quoted literals in generated Python source without escaping them. A crafted default can terminate the literal and inject statements into the generated module that execute when the module is imported.

Risk Assessment

An attacker able to influence schema default values can execute arbitrary Python code during import of the generated module, threatening system integrity and confidentiality.

Recommendation

Upgrade dataclasses-avroschema to version 0.70.6 or later, which escapes schema values rendered into generated string literals.

Original NVD description (English source)

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, FieldRepresentation.get_field_default inserts schema-controlled string, UUID, bytes, and fixed field defaults into quoted literals in generated Python source without escaping them. A crafted default can terminate the literal and inject statements into the generated module, which execute when the module is imported. Version 0.70.6 fixes the vulnerability by escaping schema values rendered into generated string literals.
