OpenAI delivered a working fix for BioShocking in ChatGPT Atlas, closing a prompt-injection path that could push an AI browser toward unsafe real-world actions and credential theft. The mitigation addresses a concrete agentic-browser safety weakness that researchers showed across six mainstream products. OpenAI was the only vendor reported to have implemented an effective fix after receiving the disclosure.

    OpenAI fixes BioShocking in ChatGPT Atlas

    Mitigation Patch Update

    LayerX says OpenAI implemented a working fix for the BioShocking prompt injection issue in the ChatGPT Atlas browser after the disclosure of a malicious webpage PoC that pushed agentic browsers toward unsafe real-world actions. The same report says Anthropic's patch for the Claude Chrome plugin was ineffective and Perplexity AI closed the report without fixing the issue.
