Who can exploit CVE-2026-23498

Access: A high-privilege account in the app, such as an admin.

CVSS vector (scored by NVD): CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

Your app is only exposed if it uses the affected part of shopware/core. The advisory below says which part that is. If you are not sure, upgrade anyway: it costs less than finding out.

How to fix CVE-2026-23498 in shopware/core

Find the installed version: composer show shopware/core. If you never required it yourself, composer why shopware/core shows which package pulls it in.
Update it: composer update shopware/core --with-all-dependencies. You need 6.7.6.1 or newer.
If Composer will not go that high, your composer.json constraint is holding it back. Widen it (for example "shopware/core": "^6.7.6.1" if you can take that version), or upgrade the package that requires it.
Run composer audit. It reads the same advisory data and should no longer list CVE-2026-23498.
Commit composer.lock and deploy it. On the server, run composer install --no-dev from the lock file, not composer update.

If you cannot upgrade yet

General hardening for remote code execution issues while the upgrade waits. None of it replaces the fix.

Never pass user-controlled data to unserialize() or to template rendering, and restrict who can edit templates or settings.
Put a web application firewall in front of the app and watch for new PHP files or admin users.
If your app does not use the affected feature, note that in your audit, but still plan the upgrade.
