9 November 2026Claude Code stores approved commands containing passwords in settings.local.json

If you choose "Yes, and don't ask again" in Claude Code, the tool saves the command verbatim in .claude/settings.local.json, including passwords or API keys. Apiiro found real secrets in 1,122 of 104,185 public copies on GitHub, including 379 database passwords.

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.

November 2 2026Message threads (beta) fall outside Zero Data Retention

With message threads in the Claude API, Anthropic stores the conversation, the system prompt and the tools on the server, encrypted in memory and not on disk, until up to one hour after the last use. The feature does not qualify for Zero Data Retention; your other ZDR agreements still apply. If you work with personal data under ZDR, only enable threads if your DPIA covers it. source
