Is PubPeer safe?
PubPeer queries its API on each page load and injects comment-link banners into matching academic publication pages.
On every page load, PubPeer sends the current URL to pubpeer.com/v3/publications to check for associated peer-review comments. When comments exist, the extension injects a banner into the page with links back to PubPeer. A URL value returned by the API is embedded into the banner's innerHTML without sanitization in the retracted/flagged-publication code path, which could allow a malformed API response to inject content into the visited page.

The PubPeer Foundation - no other listings under this identity, 1 shared hostname
What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 1 hostname
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.

Where it sends data
Destinations our analysis observed PubPeer contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
