OpenAI introduced Lockdown Mode to limit ChatGPT's outbound network access and mitigate data exfiltration from prompt-injection attacks, and added an Active Sessions feature for users to audit signed-in devices. Lockdown Mode severs exfiltration channels but disables live connectors and write actions; Active Sessions allows session termination but omits SSO accounts, third-party apps and certain CLI logins.
