Copilot chatbot vulnerable to prompt injection attacks

By PulseAugur Editorial · [1 sources] ·

A security researcher discovered a prompt injection vulnerability in the Copilot chatbot, allowing attackers to manipulate its responses. By altering client-provided context parameters like `pageText` and `currentUrl`, an attacker can trick the AI into validating fake security updates or phishing links.
