What happened

A broad set of high-risk incidents and vulnerabilities was reported: Russian intelligence‑affiliated actors are conducting mass phishing campaigns to compromise commercial messaging apps (Signal, WhatsApp) for account takeovers; Oracle released an out‑of‑band patch for a critical unauthenticated RCE in Identity Manager/Web Services Manager (CVE-2026-21992, CVSS 9.8); the Trivy supply‑chain and its GitHub Actions were compromised, leading to CI/CD secret theft and a self‑propagating npm worm dubbed CanisterWorm. Multiple high‑severity/critical flaws are being actively exploited or added to CISA
