    Starting from version 2.52.0, WebKitGTK can no longer be backported to     the oldstable distribution (bookworm). Because of that, the webkit2gtk     packages are no longer covered by security support in bookworm.

    For the stable distribution (trixie), these problems have been fixed in     version 2.52.1-1~deb13u1.

    We recommend that you upgrade your webkit2gtk packages.
