Executive Summary

ConvertX before version 0.19.0 has a vulnerability where recipe files (with .recipe or .downloaded_recipe extensions) are not blocked and are passed to the ebook-convert program from Calibre. This allows executable code in these files to run, potentially leading to unauthorized actions or system compromise.

Detection Guidance

Check if ConvertX version is below 0.19.0 by running: convertx --version. Inspect recipe files (.recipe or .downloaded_recipe) in your system for executable code. Review logs for ebook-convert program calls from ConvertX.

Impact Analysis

This vulnerability could allow attackers to execute arbitrary code on your system if you process untrusted recipe files. It may lead to data breaches, system compromise, or unauthorized access to sensitive information. The high CVSS scores (9.4 v4.0, 9.9 v3.1) indicate severe impact.

Compliance Impact

This vulnerability could violate compliance requirements under GDPR and HIPAA by enabling unauthorized access to personal or health data. Organizations processing such data must ensure systems are patched to prevent breaches that could lead to regulatory penalties.

Mitigation Strategies

Upgrade ConvertX to version 0.19.0 or later. Remove or block .recipe and .downloaded_recipe files from processing. Monitor for unauthorized ebook-convert executions.
