Prolific Microsoft 0-day hunter drops CrowdStrike Falcon exploit PoC

Researcher Nightmare Eclipse released a PoC for FalconFlank, a privilege escalation zero-day in CrowdStrike Falcon's Office macro remediation feature.

Researcher Nightmare Eclipse published a zero-day PoC dubbed FalconFlank targeting CrowdStrike Falcon's Microsoft Office malicious macro removal feature, achieving privilege escalation on fully updated Windows 11 25H2 and Windows Server 2025 with Optimal Protection and macro removal enabled. Kevin Beaumont independently confirmed the exploit works. The same researcher also released HardBreacher, an elevation-of-privilege bug in Kaspersky Endpoint (since fixed via update), PrettyPrague, an Avast Sandbox flaw that dumps the SAM database for a SYSTEM shell (Gen Digital is developing a patch), and GreenSection, an Nvidia memory corruption bug that crashes systems. CrowdStrike advises customers to disable the Suspicious Macro Removal Windows policy while it investigates.

Critical Gitea RCE Actively Exploited as Reported Attack Drops Miner

CISA added actively exploited Gitea RCE CVE-2026-60004 (CVSS 9.8) to the KEV catalog as attackers deploy a cryptojacking dropper.

CVE-2026-60004 is a critical remote code execution flaw affecting Gitea versions 1.17 through 1.27.0, abused via the diffpatch endpoint to install a Git hook and execute shell commands as the Gitea OS user. Default open registration lets unauthenticated attackers obtain the required repository write access. CISA added the flaw to its Known Exploited Vulnerabilities catalog, giving federal agencies until August 28, 2026 to patch; version 1.27.1 fixes it. A developer reported their HOSTKEY-hosted VPS was exploited to run a miner-like dropper, driving CPU usage above 70% and killing competing processes.
