  We report that ChatGPT 4 and 4o are susceptible to a prompt injection attack
that allows an attacker to exfiltrate users' personal data. It is applicable
without the use of any 3rd party tools and all users are currently affected.
This vulnerability is exacerbated by the recent introduction of ChatGPT's
memory feature, which allows an attacker to command ChatGPT to monitor the user
for the desired personal data.
