Summary
The (1) JScript 5.8 and (2) VBScript 5.8 scripting engines in Microsoft Windows Server 2008 R2 and Windows 7 do not properly load decoded scripts obtained from web pages, which allows remote attackers to trigger memory corruption and consequently obtain sensitive information via a crafted web site, aka "Scripting Engines Information Disclosure Vulnerability."
Exploit prediction
17.03% chance of exploitation in the next 30 days, higher than 97% of all scored CVEs (FIRST EPSS, 2026-11-09).
