Is Super PDF Split Merge safe?

Low risk

Super PDF Split Merge lets any embedding website trigger downloads through its web-accessible option page.

The extension exposes its option page to all websites and listens for postMessage commands without checking where they came from. A website that embeds that page can send a download command with base64 file content, causing the extension to create a blob and start a browser download named abcd.pdf.
