CVE-2026-63720 Detail

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.
