Executive priority
Handle through normal vulnerability management unless the affected app is used with sensitive data. Prioritize confirmation of installed versions and application of Microsoft guidance.
Technical view
CVE-2021-40448 affects Microsoft Accessibility Insights for Android version 2021.0.0. CVSS 3.1 score is 6.3 with AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N. The issue impacts confidentiality only, with no integrity or availability impact stated. No CWE is provided in the source bundle.
Likely exposure
