Technical details
The EnumRepresentation.render_symbols method concatenates schema-controlled enum symbol values directly between double quotes without escaping, allowing a quote character in an enum symbol to terminate the string literal and inject arbitrary Python code into the generated enum class body. When the generator classes are used directly to consume untrusted schemas, this code executes at module import time. The vulnerability also affects other schema values including record namespaces, docs, defaults, and field descriptions. Version 0.70.6 fixes this by escaping values with json.dumps and validating names in identifier positions.
