Summary
Cross-Site Scripting in ngx-md
Details

Versions of ngx-md prior to 6.0.3 are vulnerable to Cross-Site Scripting. Links are not properly restricted to http/https and can contain JavaScript which may lead to arbitrary code execution. Markdown input such as [Click Me](javascript:alert('Injected!'%29) is rendered as a Click Me link that executes JavaScript.

Recommendation

Upgrade to version 6.0.3 or later.
