Cybersecurity researchers have disclosed details of a vulnerability in OpenAI ChatGPT that leverages the artificial intelligence (AI) assistant’s implicit trust in Markdown links and images to trigger prompt injections and open the door to phishing attacks.<\/p>\n

The technique has been codenamed ChatGPhish by Permiso Security.<\/p>\n

“The chatgpt.com response renderer trusts Markdown links and Markdown image URLs that originated from a third-party page the assistant has just summarized. It auto-fetches those images and surfaces those links as live, clickable elements inside the trusted assistant UI,” security researcher Andi Ahmeti said in a report shared with The Hacker News.<\/p>\n

In a hypothetical attack scenario, a bad actor can append a small payload to any web page that the victim later prompts ChatGPT to summarize, causing it to leak their IP, User-Agent, and Referer details when attacker-hosted images embedded in the page are automatically fetched when the answer is rendered.<\/p>\n

In addition, it can result in malicious Markdown links being rendered as live clickable elements inside the assistant’s response, serve far fake system-style security alerts, and serve a QR code from an attacker’s S3 bucket and trick the victim into scanning it via their mobile device, effectively bypassing desktop URL filters and enterprise security controls.<\/p>\n

The latest finding demonstrates how summarization can emerge as an adversarial surface. Earlier this March, Permiso also revealed how an attacker-controlled email containing specially crafted instructions, when summarized by Microsoft Copilot, could influence its output via a cross-prompt injection (XPIA) or indirect prompt injection.<\/p>\n

What makes ChatGPhish a noteworthy attack technique is not the prompt injection itself, but in the manner in which the instructions embedded in a web page are followed and presented to the user as part of the summary.<\/p>\n

In other words, a regular web page summarized with ChatGPT is enough to render phishing…<\/p>\n
