Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

dataclasses-avroschema 能够从 Python dataclass、Pydantic 模型以及 Faust Records 生成 Avro 架构,并能从 Avro 架构生成 Python 代码。在 0.38.0 至 0.70.5 版本中,BaseGenerator.parse_fixed 方法会将固定类型(fixed type)的 aliases 值直接插值到生成的 types.con_fixed 注解中。当 aliases 值为列表时,其元素会以带引号的字符串形式表示;但如果是一个裸字符串(b

Vulnerability Title
dataclasses-avroschema allows code injection through generated field-default literals
Source: CVE Program / CVE List V5
Vulnerability Description
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.
