CVE-2026-108383

HighCVSS 8.8
Published: Translated: NVD NIST

Summary

The dataclasses-avroschema library versions 0.38.0 through 0.70.5 does not validate the default value of an enum field as an identifier, allowing injection of statements into the generated module. This can lead to namespace modification or prevent the module from loading.

Risk Assessment

An attacker able to supply a crafted Avro schema can influence the generated Python code, potentially causing namespace modification or module failure.

Recommendation

Update the dataclasses-avroschema library to version 0.70.6 or later, which validates enum defaults as names.

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 renders a schema-controlled enum field default as an enum member reference after applying case conversion but without validating it as an identifier. Newlines, operators, and punctuation can escape the intended reference and inject constrained statements into the generated module, allowing namespace modification or preventing the module from loading. Version 0.70.6 fixes the vulnerability by validating enum defaults as names.
