KB5072014: Windows Server Security Update (November 2025)
Microsoft Windows contains a link following vulnerability that allows for privilege escalation
A local attacker, with a low-privilege account, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. Federal agencies are required to remediate by 2026-04-27 under CISA BOD 22-01.
This is a Software Vulnerability (CWE-59) (CWE-59) vulnerability in Microsoft Windows. Improper link resolution before file access ('link following') in Host Process for Windows Tasks allows an authorized attacker to elevate privileges locally. Exploitation requires local access, low attack complexity, a low-privilege authenticated account, and no user interaction required.
Probably yes if any of these apply:
CISA added this CVE to the Known Exploited Vulnerabilities catalog on 2026-04-13 based on evidence of active exploitation in the wild. Federal agencies required to remediate by 2026-04-27.
