ChatGPT is expanding access to Lockdown Mode and Active Sessions, tightening protection against prompt-injection data exfiltration and account/session compromise. Lockdown Mode limits outbound network requests and restricts features that could move sensitive data off the platform. Active Sessions lets users review signed-in devices and log out sessions they do not recognize.

    OpenAI rolls out ChatGPT Lockdown Mode and Active Sessions

    Mitigation Patch Update

    OpenAI is broadly rolling out ChatGPT Lockdown Mode for personal and self-serve Business accounts and Active Sessions for most ChatGPT accounts, adding controls that limit outbound network requests to reduce prompt-injection data exfiltration risk and let users review signed-in devices and log out unfamiliar sessions. The rollout follows Advanced Account Security for higher-risk users, which requires physical security keys or passkeys and shortens sign-in sessions.
