YellowKey Exploit Exposes TPM-Only BitLocker Gaps in Modern Windows Systems

Microsoft issued a mitigation for CVE-2026-45585 (YellowKey), a zero-day BitLocker bypass allowing physical-access attackers to trigger an unrestricted shell in WinRE via USB-delivered FsTx files and CTRL key input. The flaw affects Windows 11 versions 24H2, 25H2, 26H1 and Windows Server 2025, revealing a critical limitation in TPM-only encryption that requires multi-factor pre-boot authentication to fully mitigate.

Active Exploitation of Nginx Flaws Demands Urgent Patching Across Global Web Infrastructure

GovCERT.HK's High Threat Security Alert (A26-05-36) confirms active exploitation of CVE-2026-42945, a denial-of-service and remote code execution vulnerability in Nginx, affecting stable versions prior to 1.30.1 and mainline prior to 1.31.0. The alert references six CVEs spanning memory safety, input validation, and configuration flaws, with potential impacts including full system compromise, service disruption, and data exfiltration. Given Nginx's pervasive role as a reverse proxy, load balancer, and ingress controller in enterprise, cloud, and containerized environments, the vulnerability presents a critical initial access vector for threat actors. Immediate patching is urged, with defenders advised to verify patch status across public-facing, internal, and cloud-deployed instances while monitoring for exploit indicators in logs and network traffic.

Weaponization of CVE-2026-42945: NGINX Rewrite Module Vulnerability Under Active Exploitation

A critical security flaw impacting NGINX Plus and NGINX Open Source, tracked as CVE-2026-42945, has transitioned from public disclosure to active exploitation in the wild. The vulnerability is a heap buffer overflow within the ngx_http_rewrite_module that allows unauthenticated attackers to trigger worker process crashes (denial-of-service) or potentially achieve remote code execution (RCE) via crafted HTTP requests. While RCE is largely mitigated by Address Space Layout Randomization (ASLR), honeypot data confirms threat actors are already weaponizing the flaw to disrupt services. This exploitation coincides with a cluster of attacks targeting openDCIM infrastructure management software, reportedly utilizing AI-assisted vulnerability discovery tools. F5 has released patches, and immediate updates are recommended for all NGINX deployments within the affected version range (0.6.27 to 1.30.0). Read more
