  "textContent": "wiredmikey shares a report from SecurityWeek: Microsoft on Wednesday published an advisory acknowledging the public disclosure of a vulnerability in Defender that could lead to privilege escalation. The security defect, tracked as CVE-2026-50656 (CVSS score of 7.8), was dropped last week by security researcher Nightmare Eclipse (also known as Chaotic Eclipse). \"We are working to provide a high-quality security update that addresses this vulnerability. We will provide information in this CVE when the update is available,\" Microsoft adds. RoguePlanet, Nightmare Eclipse explained last week, targets a race condition in Microsoft Defender and allows attackers to gain System privileges. The researcher released a proof-of-concept (PoC) exploit that demonstrates local privilege escalation (LPE) on Windows 11 and Windows 10 systems with the June 2026 patches installed. [...] On Wednesday, Nightmare Eclipse pointed out that the PoC works regardless of whether Defender's real-time protection is enabled or disabled. It may even work in passive mode, the researcher said.\n\nRead more of this story at Slashdot.",
