Zoom Workplace for Android Privilege Escalation Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2025-64741

The vulnerability affects Zoom Workplace for Android, which is a client-side end-user application. Client applications are typically installed on personal mobile devices and are not designed to serve as internet-facing services, gateways, or APIs. Therefore, it is highly unlikely to be exposed as a public-internet-facing attack surface in common deployments.

Frequently asked questions

What is Zoom Workplace for Android?

Zoom Workplace is a unified communications platform used for video conferencing, team chat, and collaboration. The Android version acts as a mobile client application that connects to the Zoom ecosystem. It relies on internal components to manage user sessions and permissions. CVE-2025-64741 concerns these Android-based client versions, specifically affecting how the software handles authorization logic on mobile devices.

What does improper authorization mean for CVE-2025-64741?

This vulnerability falls under CWE-74, which involves the improper neutralization of data used in an authorized context. For this CVE, it means the application fails to correctly verify the identity or permissions of a user requesting specific actions. Because of this flaw, an unauthenticated user could bypass standard security checks, tricking the application into performing tasks or granting access that should normally require elevated privileges.

How can an attacker trigger this vulnerability?

An attacker needs network access to the target device to initiate an exploit. This generally involves sending specially crafted network requests to the vulnerable Zoom application. Simply browsing or using the application normally does not trigger the bug; the attacker must be able to reach the application's network interface directly to exploit the authorization weakness while the software is active.

Do I need to worry if I use this app on my phone?

According to Halo Surface Signal, it is very unlikely that your mobile device acts as an internet-facing service or gateway. While the vulnerability is critical, it exists in a client-side end-user application rather than a public-facing server. Most users do not expose their mobile apps to direct incoming network traffic from the open internet, which significantly lowers the risk for typical personal or corporate mobile deployments.

When should I update Zoom Workplace?

You should update to version 6.5.10 or later as soon as it becomes available through your app store or device management system. If you manage a fleet of devices, prioritize identifying which handsets run versions older than 6.5.10. Once identified, coordinate the update process to ensure all affected instances of the Zoom client are patched, closing the authorization gap before any potential network-based attempt can occur.
