Is Qwer PDF safe?
Qwer PDF forwards all postMessage events from any web page to its service worker without validating the sender's origin.
The extension's content script runs on every web page and listens for postMessage events. The origin check that would restrict messages to qwerpdf.com is commented out, so any page can trigger service worker actions including file uploads to qwerpdf.com servers and overwriting stored user credentials.
Part of this rating comes from analysis signals we haven't published as detailed findings yet.

What this publisher told the store about itself, and the other listings that told it the same thing.
Same store account
7 other listings published from this account, 140k+ users between them. 1 of them carries a finding.
Shared hosts - 4 hostnames
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
