Why it matters
This code injection vulnerability can lead to Remote Code Execution (RCE), allowing attackers to execute arbitrary Python code on systems using datamodel-code-generator prior to version 0.70.0. A successful exploit could result in full system compromise, data exfiltration, or further network penetra
Recommended admin actions
- Upgrade datamodel-code-generator to version 0.70.0 or later immediately.
- Identify all instances of datamodel-code-generator running in your environment.
- Restrict access to input schemas for the datamodel-code-generator to trusted sources only.
- Monitor application logs for any signs of unusual Python code execution or related errors.
Technical summary
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.

About the Vulnerability Pulse CVE Feed
The Vulnerability Pulse feed tracks live CVE advisories sourced from the National Vulnerability Database and vendor security disclosures. It is designed for SOC analysts, IT administrators, and security teams who need a fast, filterable view of current vulnerabilities without digging through raw NVD data.
How to Use the CVE Advisory Tracker
Use the severity filters to narrow results to Critical or High priority vulnerabilities. Filter by vendor to focus on software and hardware relevant to your environment. Export to CSV for reporting, ticketing, or patch prioritization workflows.
What Is a CVE Advisory?
A CVE (Common Vulnerabilities and Exposures) advisory is a public disclosure of a security vulnerability assigned a unique identifier by MITRE. Advisories include severity scores (CVSS), affected versions, and remediation guidance. Monitoring CVE advisories is a core function of vulnerability management programs and SOC operations.
CVE Analysis & Writeups
For in-depth analysis of specific vulnerabilities, visit the IT Knowledge Bases blog for CVE breakdowns, exploitation analysis, and remediation guidance written for security practitioners.
