The Indian Computer Emergency Response Team (CERT-In) has issued a serious security warning for Zoom users across multiple platforms, including Windows, macOS, Android, iOS, and Linux. With Zoom still being one of the most popular platforms for video calls, online classes, and business meetings, this alert is a major concern for both personal and professional users.
What the Government Alert Says
CERT-In’s September advisory reveals that multiple security vulnerabilities exist in Zoom products. These include:
- Weak authorization checks
- Race conditions
- Unsafe handling of user data
- Boundary errors
- Missing security mechanisms
- Argument injection risks
These flaws carry a high-severity rating, meaning hackers could exploit them to gain access to user devices, steal sensitive data, or disrupt business operations.
Who Is Affected?
The security risk is not limited to one platform — it affects a wide range of Zoom apps and plugins.
Vulnerable Zoom Versions Identified by CERT-In:
- Zoom Workplace VDI Plugin (macOS Universal installer for VMware Horizon) – before version 6.4.10 (or before 6.2.15 / 6.3.12 in respective tracks)
- Zoom Workplace Desktop (Windows) – before version 6.5.0
- Zoom Workplace VDI Client (Windows) – before versions 6.3.14 and 6.4.12
