Deeper analysis
CVE-2026-32200 is a use-after-free vulnerability (CWE-416) in Microsoft Office PowerPoint, published on 2026-04-14. The flaw allows an unauthorized attacker to execute code locally and has a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high severity due to substantial impacts on confidentiality, integrity, and availability.
An unauthorized local attacker can exploit this vulnerability by tricking a user into performing an action, such as opening a malicious PowerPoint file, given the requirements for local access, low attack complexity, no privileges, and user interaction. Successful exploitation enables arbitrary code execution on the affected system with high-impact privileges.
Microsoft's Security Response Center provides detailed mitigation guidance, including patches, in their update guide at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-32200.
