Overview
Affected versions of this package are vulnerable to Protection Mechanism Failure in the iframe sandboxing process. An attacker can bypass intended security restrictions by tricking a user into processing or loading malicious web content. This is only exploitable if the system is configured with certain packages that require WebKitGTK4 and are used via a graphical interface to process untrusted web content, such as through GNOME. In some cases, exploitation may be possible from the local network without user interaction.
Workaround
This vulnerability can be mitigated by removing packages that require WebKitGTK4 or by avoiding the processing or loading of untrusted web content.
