Microsoft Teams Android Vulnerability (CVE-2026-32185) Exposes Users to Spoofing Attacks
On May 12, 2026, Microsoft disclosed CVE-2026-32185, a security flaw in Microsoft Teams for Android that could enable attackers to spoof local devices and manipulate trusted application elements. The vulnerability was revealed as part of Microsoft’s May 2026 Patch Tuesday updates.
The issue stems from improper file and directory access controls in Teams, allowing unauthorized local attackers to impersonate legitimate content and deceive users into interacting with malicious communications. While exploitation requires user interaction and is confined to a local attack vector, the flaw poses a high risk to data confidentiality, particularly in enterprise environments.
With a CVSS 3.1 base score of 5.5 (adjusted environmental score: 4.8) and a severity rating of Important, the vulnerability does not require elevated privileges, lowering the barrier for exploitation in shared or compromised local environments. Microsoft’s assessment categorizes the flaw as "Exploitation Less Likely", and no active exploitation or proof-of-concept code has been confirmed.
The vulnerability affects Microsoft Teams for Android, with the patched version (1.0.0.2026092103) available via the Google Play Store. Microsoft has released an official fix, and users are advised to update immediately. Security researcher Ofek Levin of Enclave is credited with responsibly disclosing the issue.
Organizations using Teams in regulated or high-security environments, particularly on mobile devices, should prioritize applying the patch to mitigate potential risks.
