Your app is only exposed if it uses the affected part of laravel/framework. 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-2026-102279 in laravel/framework

Find the installed version: composer show laravel/framework. If you never required it yourself, composer why laravel/framework shows which package pulls it in.
Update it: composer update laravel/framework --with-all-dependencies. You need the fixed version for your release line (12.69.0 and 13.30.0).
If Composer will not go that high, your composer.json constraint is holding it back. Widen it (for example "laravel/framework": "^13.30.0" 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-2026-102279.
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 XSS issues while the upgrade waits. None of it replaces the fix.

Escape output in your own templates and add a Content-Security-Policy that blocks inline scripts.
Limit who can save the content the advisory names (for example rich text, SVG or form fields).
If your app does not use the affected feature, note that in your audit, but still plan the upgrade.
