Summary

All versions of `markdown-it-katex` are vulnerable to Cross-Site Scripting (XSS). The package fails to properly escape error messages, which may allow attackers to execute arbitrary JavaScript in a victim's browser by triggering an error.

## Recommendation

No fix is currently available. Consider using an alternative package until a fix is made available.
