## Technical details

This vulnerability is a cross-site scripting (XSS) flaw arising from improper input sanitization during web page generation in Teams for Android. An authorized attacker can inject malicious script payloads through application inputs that are rendered without proper neutralization. The attack requires the attacker to have authorized access to Teams and for a target user to view the crafted malicious content. Successful exploitation allows the attacker to perform spoofing attacks, potentially forging message origins or identities. Patches are available from Microsoft.
