CVE-2026-20644 WebKitGTK vulnerabilities
Title: WebKitGTK vulnerabilities
Summary: Several security issues were fixed in WebKitGTK.
Several security issues were discovered in the WebKitGTK Web and JavaScript
engines. If a user were tricked into viewing a malicious website, a remote
attacker could exploit a variety of issues related to web browser security,
including cross-site scripting attacks, denial of service attacks, and
arbitrary code execution.
Instructions: This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart any applications
that use WebKitGTK, such as Epiphany, to make all the necessary changes.
