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.

For the detailed security status of webkit2gtk please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/webkit2gtk
