AI-suggested
A fix is available in datamodel-code-generator version 0.60.2. Users should upgrade to version 0.60.2 or later to remediate this vulnerability. Until upgrading, avoid importing generated models from untrusted or unsanitized --extra-template-data inputs.
Description
CVE-2026-54656 is a high-severity code injection vulnerability in koxudaxi's datamodel-code-generator affecting versions from 0.52.1 up to but not including 0.60.2. The tool generates Pydantic v2 models and other data models from various schema formats. The vulnerability arises because the software interpolates validators from the --extra-template-data option into @field_validator decorators without safe validation, allowing arbitrary Python code execution when the generated model is imported. This issue is fixed in version 0.60.2.
