Zoom Fixes Serious Flaw That Let Meeting Attendees Hack Other Participants

Zoom has released a patch for a significant security flaw found in its annotation feature, which is commonly used during meetings to mark up shared screens. The vulnerability was serious because it required no action from the victim—simply being in a meeting with a malicious participant could be enough for an attacker to execute code on another person's computer.

This type of 'zero-click' vulnerability is particularly concerning because it removes the usual safeguard of user caution. Employees are often trained to avoid clicking suspicious links or downloading unknown files, but this flaw could be exploited without any such interaction, making it harder for everyday users to protect themselves.

Zoom has now released an update that addresses the issue, and users are strongly encouraged to install it as soon as possible. Video conferencing tools remain a frequent target for attackers due to their widespread use in business communications, and prompt patching is essential to close security gaps before they can be exploited.
