Is JSON格式化工具 safe?

Clean risk

JSON格式化工具 can capture the active tab as an EPUB and upload it to the configured reMarkable cloud API.

When the user clicks the extension action, JSON格式化工具 can save the active tab as MHTML, convert it to EPUB, and send the resulting document to reMarkable if cloud upload is configured. The captured page data can include DOM content, the page title, and the URL, and the upload uses the stored reMarkable device token.

Who publishes it

CSDN - 3 other listings from the same operator, none carrying a finding

What this publisher told the store about itself, and the other listings that told it the same thing.

Publisher
CSDN

Same store account

3 other listings published from this account, 43k+ users between them, none of them carrying a finding.

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 JSON格式化工具 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.
