About this tag
Discussions on WindowsForum.com cover multiple Microsoft Office security vulnerabilities patched in the July 14, 2026 security updates, including CVE-2026-55057, CVE-2026-55129, CVE-2026-55049, CVE-2026-55028, CVE-2026-55125, CVE-2026-47290, CVE-2026-45645, and CVE-2026-44824. These flaws affect Microsoft 365 Apps for Enterprise, Office 2016, Office 2019, Office LTSC 2021, Office LTSC 2024, and Office for macOS. Common themes include information disclosure, remote code execution, and heap-based buffer overflows, with CVSS scores ranging from 5.5 to 7.8. A recurring topic is the distinction between Microsoft's "remote code execution" label and the CVSS local attack vector, which reflects that exploitation requires local processing of malicious content rather than network-based attack. Administrators are advised to apply the July 14 updates promptly.
