Is Blerp - Video Alerts, TTS, Sound Memes on Streams safe?

Medium risk

Blerp writes Blerp login tokens into twitch.tv localStorage after its Twitch login flow.

When you use the injected Blerp login widget on Twitch and click Finish Login, the extension stores the returned Blerp JWT and refresh token in twitch.tv page localStorage. The same flow contacts Blerp's GraphQL API, so the token storage happens after api.blerp.com returns the login tokens.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 16 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.
