Upgrade wpe_webkit to version 2.52.4 or higher.
Overview
Affected versions of this package are vulnerable to Improper Input Validation via improper input validation in the processing of web content. An attacker can bypass security restrictions by tricking a user into loading malicious web content, which may prevent Content Security Policy from being enforced. This is only exploitable if the system has certain packages installed and is being used via a graphical interface to process untrusted web content, such as through GNOME.
Workaround
This vulnerability can be mitigated by removing the affected packages that require WebKitGTK4 or WebKitGTK3, though this may impact system functionality, especially if GNOME is in use.
