Описание
The issue was addressed with improved handling of caches. This issue is fixed in tvOS 26.1, watchOS 26.1, macOS Tahoe 26.1, iOS 26.1 and iPadOS 26.1, Safari 26.1, iOS 18.7.2 and iPadOS 18.7.2, visionOS 26.1. A website may exfiltrate image data cross-origin.
A flaw was found in WebKitGTK. A malicious website may exfiltrate image data cross-origin due to improper handling of caches.
Отчет
To exploit this issue, an attacker needs to trick a user into visiting a malicious website, potentially exposing sensitive information. Due to this reason, this flaw has been rated with a moderate severity.
Меры по смягчению последствий
Do not visit untrusted websites. Also, do not process or load untrusted web content with WebKitGTK. In Red Hat Enterprise Linux 7, the following packages require WebKitGTK4: evolution-data-server, glade, gnome-boxes, gnome-initial-setup, gnome-online-accounts, gnome-shell, shotwell, sushi, and yelp. This vulnerability can only be exploited when these packages are installed in the system and used via a graphical interface to process untrusted web content, via GNOME, for example. In gnome-shell, the vulnerability can be exploited by an attacker from the local network without user interaction. To mitigate this vulnerability, consider removing these packages. Note that some of these packages are required by GNOME, removing them will also remove GNOME and other packages, breaking functionality. However, the server can still be used via the terminal interface. Additionally, WebKitGTK3 is not required by any package. Therefore, it can be removed without consequences or break of functionality.
