An attachment spoofing issue in WhatsApp for Windows prior to v2.3000.1032164386.258709 could have allowed maliciously formatted documents with embedded NUL bytes in the filename to be shown in the application as one type of file but run as an executable when opened. We have not seen evidence of exploitation in the wild.

CVE-2025-55177
Incomplete authorization of linked device synchronization messages in WhatsApp for iOS prior to v2.25.21.73, WhatsApp Business for iOS v2.25.21.78, and WhatsApp for Mac v2.25.21.78 could have allowed an unrelated user to trigger processing of content from an arbitrary URL on a target’s device. We assess that this vulnerability, in combination with an OS-level vulnerability on Apple platforms (CVE-2025-43300), may have been exploited in a sophisticated attack against specific targeted users.

A spoofing issue in WhatsApp for Windows prior to version 2.2450.6 displayed attachments according to their MIME type but selected the file opening handler based on the attachment’s filename extension. A maliciously crafted mismatch could have caused the recipient to inadvertently execute arbitrary code rather than view the attachment when manually opening the attachment inside WhatsApp. We have not seen evidence of exploitation in the wild.
