Short explanation
dataclasses-avroschema contains a code injection vulnerability because Pydantic and AvroDantic model generators insert pydantic-class metadata without safe restriction.
It allows attackers to execute arbitrary Python code through annotations evaluated when the generated module is imported.
What should be done?
- Upgrade to version 0.70.6 or later
- Follow vendor advisories
Chain of evidence and sources
dataclasses-avroschema kütüphanesi sürüm 0.44.0 ile 0.70.5 arasında kod enjeksiyonuna açıktır.
Sürüm 0.70.6, değeri kısıtlayarak bu zafiyeti gidermektedir.
Show the technical text from the sources
dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.44.0 through 0.70.5, the Pydantic and AvroDantic model generators insert a schema field's pydantic-class value after pydantic. in a generated field annotation without safely restricting the expression. Because annotations are evaluated when the generated module is imported, a crafted value can execute arbitrary Python code. Version 0.70.6 fixes the vulnerability by restricting the value to a bare name or a call to a bare name with literal arguments.
