Name of the Vulnerable Software and Affected Versions vmd versions through 1.34.0

Description The issue allows 'div class="markdown-body"' XSS, as demonstrated by Electron remote code execution via require('child process').execSync('calc.exe') on Windows and a similar attack on macOS.

Recommendations For versions through 1.34.0, update to a version that contains a fix for this issue to prevent XSS and remote code execution attacks.
