VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2022-48503 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
WebKitGTK3 is not required by any package. Therefore, it can be removed without consequences or break of functionality.. WebKitGTK4 is used in Red Hat Enterprise Linux 7 by the following packages: evolution-data-server, glade, gnome-boxes, gnome-initial-setup, gnome-online-accounts, gnome-shell, shotwell, sushi and…
To mitigate this vulnerability, consider removing certain GNOME packages. Note that uninstalling these packages will break functionality in GNOME, however the server can still be used via the terminal interface.Source: Red Hat security advisory for CVE-2022-48503 (CC BY 4.0)
