WhatsApp, one of the world’s most popular messaging apps, has patched a serious security vulnerability targeting Apple users. According to the company’s official announcement, this vulnerability, identified as CVE-2025-55177, was used in a sophisticated spyware attack targeting Apple devices.

WhatsApp Patches a Major Security Vulnerability

This vulnerability in WhatsApp is reportedly used in conjunction with another vulnerability in iOS and Mac devices, which Apple patched last week and tracked as CVE-2025-43300. Combined, these two vulnerabilities allowed attackers to infiltrate users’ devices using a so-called zero-click method. “Zero-click” refers to the device being compromised without the user having to click any links or download any files.

The attack reportedly allowed malicious spyware to be installed on a user’s Apple device via WhatsApp. This access to all information on the device, including messages and other personal data, was possible.

Apple previously stated that this vulnerability was used in “an extremely sophisticated attack targeting specific target individuals.” WhatsApp’s latest announcement confirms that these attacks target WhatsApp users.

It is currently unknown which group or spyware vendor is behind the attacks. However, the swift response of WhatsApp and Apple prevented the potential threat from spreading. Users are strongly encouraged to update their WhatsApp apps and iOS/Mac operating systems to the latest versions for their safety.
