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

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-2026-31887 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 the fixed version for your release line (6.6.10.15 and 6.7.8.1).
If Composer will not go that high, your composer.json constraint is holding it back. Widen it (for example "shopware/core": "^6.7.8.1" 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-2026-31887.
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 missing authorization issues while the upgrade waits. None of it replaces the fix.

Remove accounts you do not need and review what each role can do.
Put the admin area behind a VPN, IP allow-list or extra login until you upgrade.
If your app does not use the affected feature, note that in your audit, but still plan the upgrade.
