CVE-2026-54654Public exploit

Python code execution via carriage-return injection

Published Jul 28, 2026 · Updated Jul 28, 2026

Code injection in koxudaxi datamodel-code-generator 0.14.1 through 0.60.1 allows attackers to execute Python via a crafted extras file. Built-in Jinja2 templates interpolate the comment value into a Python # comment without neutralizing a bare carriage return, so following text becomes executable source. Exploitation requires a developer or CI pipeline to process an attacker-influenced --extra-template-data file and import the generated model, granting code execution in that process.
