CVE-2026-41102 is a local spoofing vulnerability in Microsoft PowerPoint for Android caused by improper access control in a shared Microsoft 365 Android SDK. According to the provided reporting, a production debug setting (setIsDebugMode(true)) was left enabled, which disabled the trust verification step intended to ensure that only trusted Microsoft applications could participate in Microsoft account token sharing. As a result, a malicious third-party Android application installed on the same device could request and obtain the signed-in user’s Microsoft account token from PowerPoint without a password prompt, login prompt, permission prompt, or other user interaction. The issue is part of the broader "FlagLeft" research affecting multiple Microsoft 365 Android apps that relied on the same shared SDK logic. Microsoft classified CVE-2026-41102 as a spoofing vulnerability under CWE-284 and scored it CVSS 7.1 with local attack vector, low attack complexity, low privileges required, and no user interaction.
