GHSA-P7C9-JQHQ-VR3V

Vulnerability from github – Published: 2018-07-27 17:03 – Updated: 2023-03-01 01:36

Summary

Remote Code Execution in markdown-pdf

Details

Versions of markdown-pdf prior to 9.0.0 are vulnerable to Remote Code Execution. The package fails to sanitize HTML code in markdown files. If markdown files with malicious HTML are converted to PDF, the resulting PDF file will execute any JavaScript code in the original markdown file. This may allow attackers to execute Remote Code.

Recommendation

Upgrade to version 9.0.0 or later.

Severity ?

5.5 (Medium)
