OpenAI’s Atlas Browser Faces Backlash Over Prompt Injection Threats

October 24, 2025

OpenAI’s newly launched ChatGPT Atlas browser is drawing scrutiny from experts, who warn that unresolved prompt injection vulnerabilities pose particular risks for crypto users.

Key points:

  • OpenAI’s ChatGPT Atlas browser faces criticism as experts highlight unresolved prompt injection vulnerabilities that could expose sensitive user data.
  • Prompt injections can trick the AI assistant into executing hidden commands, potentially leaking credentials, autofill data, or session information.
  • The rapid adoption of AI browsers like Atlas increases the potential impact of these vulnerabilities, making user caution and awareness more critical than ever.

Within hours of its launch, security researchers had already uncovered several vulnerabilities in the system. Demonstrations showed that attackers could exploit the browser to hijack clipboard data, alter browser settings through seemingly harmless platforms such as Google Docs, and embed hidden commands designed to facilitate phishing schemes.

Security researchers warn that a single hidden line of text on a website could trick an AI assistant into leaking private information. For example, when a user opens OpenAI’s new Atlas browser and asks its assistant to summarize a coin review the tool scans the page and generates a response.


However, if a webpage discreetly embeds an instruction directing the assistant to, for instance, “complete a survey” and include the user’s saved logins or autofill information, the browser could misinterpret it as a legitimate command. In doing so, the assistant might go beyond summarizing the content and inadvertently disclose sensitive data, such as stored credentials, autofill details, or indicators that the user is signed into accounts like Coinbase.

This type of manipulation, known as a “prompt injection,” spotlights a critical flaw: AI systems that treat all on-page text as trustworthy instructions. Once a rarity due to the limited adoption of AI browsers, the threat now carries greater weight.

A cybersecurity researcher using the X handle P1njc70r clarified a previous post regarding the vulnerabilities of OpenAI’s Atlas browser. While initially stating that the browser was susceptible to prompt injections, the researcher later explained that prompt injections are not inherently harmful on their own. Instead, they can act as a gateway for exploiting other security weaknesses, and no definitive solution exists, every LLM or LLM-powered application remains vulnerable to some extent.

The ongoing debate over AI browser security spotlights the urgent need for robust standards and vigilant oversight as these tools become more integrated into daily digital life.
