VulnerabilityCVE-2026-108377cvecve-2026-108377cwe-94
Published: 10/13/2026 (10/13/2026, 17:22:32 UTC)
Source: CVE Database V5
Vendor/Project: marcosschroh
Product: dataclasses-avroschema

Description

dataclasses-avroschema generates Avro schemas from Python dataclasses, Pydantic models, and Faust Records and generates Python code from Avro schemas. From version 0.62.3 through 0.70.5, ClassRepresentation.render_metaclass inserts a schema-controlled Avro record name into the quoted Meta.schema_name field of generated Python source without escaping it. A crafted name can terminate the string literal and inject statements into the generated class body, which execute when the generated module is imported. Version 0.70.6 fixes the vulnerability by escaping schema values rendered into generated string literals.
