Indirect Prompt Injection via YouTube Transcripts
Summary
ChatGPT can access YouTube transcripts through plugins, which is useful but creates a security risk called indirect prompt injection (hidden instructions embedded in content that an AI reads and then follows). Attackers can hide malicious commands in video transcripts, and when ChatGPT reads those transcripts to answer user questions, it may follow the hidden instructions instead of the user's intended request.
