Good morning. Start with the issue most likely to change what your team needs to pay attention to today, then move through the rest in under five minutes.

Lead Story

Metabase SQLi zero-day exploited in customer data-theft attacks

Metabase SQLi zero-day exploited in customer data-theft attacks

Metabase says attackers used an unauthenticated SQL injection flaw in versions 1.58 and later to compromise Metabase Cloud, and self-hosted instances are affected too. Framework and Tally disclosed data-theft impact.

Why it matters: Admin access to Metabase exposes stored credentials for every connected database.

“Keep going, bro. You’ve got this!” A data-driven look at how adversaries are weaponizing AI

Talos analyzed prompt logs from attacker machines running Claude Code, Codex, Cursor and Gemini. Simple claims of ownership or bug-bounty framing got past guardrails, and an actor’s skill decided how much damage the AI help did.

Why it matters: Weak actors become more productive and strong actors faster.

Recommended action: Treat AI prompt logs found during incident response as evidence of intent and targets.
