Is Overleaf Copilot safe?

Medium risk

Overleaf Copilot sends IHEP chat prompts and a bundled bearer token to docsai.ihep.ac.cn over HTTP.

When its IHEP bot mode handles a chat request, Overleaf Copilot concatenates the chat messages into a query and posts them to an IHEP Docs AI endpoint using a bundled bearer token. The extension package also includes reusable IHEP and BigModel API credentials, with the BigModel key used for open.bigmodel.cn requests in BJTU or IHEP institute modes.
