5 November 2026Flaw in Lockdown Mode patched

Via pop-up windows in the HTML preview of code blocks, an attacker could bypass Lockdown Mode and siphon off your chat history, via a manipulated prompt, GPT or shared chat. OpenAI patched the flaw on 18 September 2026; Check Point published the details on 5 November. Users do not need to do anything. source

1 November 2026Reports to the police and stricter rules for teens

In the third quarter of 2026, OpenAI made more than 200 reports to law enforcement about threatened violence based on ChatGPT conversations. Conversations in which someone appears fixated on violence may be ended automatically by ChatGPT, and if it happens repeatedly, OpenAI can pause the account. So don't assume that what you type into ChatGPT stays confidential. source

ChatGPT can use plugins to search and summarise iCloud mail and change appointments, including on the free subscription. Signing in uses an app-specific password from Apple; it remains valid if you disconnect the integration in ChatGPT and you must revoke it yourself via account.apple.com. source
