Is VideoSeek Al - Video Summarizer for YouTube safe?

Low risk

VideoSeek AI removes the Content-Security-Policy header on TikTok, YouTube, Bilibili, Douyin and Xiaohongshu pages.

On install, the extension adds persistent rules that strip the Content-Security-Policy header from main-page loads on five video sites, regardless of whether it is in use. Its content script also forwards messages from page scripts to background actions, including credentialed fetches to a caller-supplied URL, opening tabs and reading cookies for permitted hosts, without checking where the message came from.

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