High · 7.5 Public exploit CVE-2026-63720 EUVD-2026-49050GHSA-7x49-hhjc-29rg

datamodel-code-generator Code Injection via Unvalidated customBasePath Schema Field

Published Jul 26, 2026 · Updated Aug 14, 2026 · Assigned by VulnCheck

Vendor: koxudaxi Product: datamodel-code-generator

Description

datamodel-code-generator prior to version 0.70.0 contains a code injection vulnerability that allows attackers who control input schemas to achieve remote code execution by supplying a malicious customBasePath value containing embedded newlines and a dot-free Python expression. The crafted value is emitted verbatim into a generated 'from ... import ...' statement without identifier validation, causing arbitrary Python code to execute when the generated module is imported.
