Outdated Laravel Version: How to Upgrade to a Supported Release for Security Patches
Running a Laravel version below current LTS means you are no longer receiving security patches. Upgrade to stay protected against published vulnerabilities.
Laravel's release cycle provides bug fixes for 18 months and security fixes for 2 years following each major release. Once a version passes its security support end date, the Laravel team no longer issues patches for newly discovered vulnerabilities. Published CVEs accumulate without fixes. Framework code that was acceptable when your application was deployed becomes increasingly dangerous as the security community discovers and documents new attack techniques against its patterns.
Attackers maintain databases of vulnerabilities by framework version. When a new Laravel CVE is published, automated scanners immediately begin probing the internet for applications identifying themselves as the vulnerable version (via response headers, error pages, or predictable file patterns). End-of-life versions accumulate multiple unpatched CVEs simultaneously — an attacker targeting an end-of-life application has a menu of known exploits to try. The risk compounds over time: a Laravel 9 application in 2026 is exposed to every CVE published since it reached end-of-life, none of which have patches.
The practical challenge of upgrading is real: breaking changes between major versions require code updates, dependency compatibility must be resolved, and testing takes time. The Laravel team has invested significantly in making upgrades predictable through detailed upgrade guides, and tools like Laravel Shift automate the majority of mechanical changes. The effort of a major version upgrade is substantial but bounded. The ongoing cost of running end-of-life software is unbounded: growing attack surface, increasing incompatibility with modern packages and PHP versions, and eventual forced migration under worse circumstances.
The Problem
Laravel provides bug fixes for 18 months and security fixes for 2 years after each major release. Once a version leaves the security support window, published vulnerabilities are never patched. Attackers specifically target end-of-life frameworks because the vulnerabilities are documented and guaranteed to be unpatched. Running an unsupported Laravel version means every new CVE affects you permanently.
How to Fix
-
1
Check your current Laravel version
Determine your installed version:
php artisan --version # Or composer show laravel/framework | grep versionsCurrent Laravel support status (as of 2026): - Laravel 12.x — Active support (current) - Laravel 11.x — Security fixes until March 2027 - Laravel 10.x — Security fixes ended February 2026 - Laravel 9.x and below — End of life, no patches
If you are on 10.x or below, upgrade immediately.
-
2
Follow the official upgrade guide
Laravel publishes detailed upgrade guides for each major version:
1. Read the upgrade guide at laravel.com/docs/[version]/upgrade 2. Update composer.json dependencies 3. Run composer update 4. Apply breaking changes documented in the guide 5. Run your test suite
# Typical composer.json change for 11 → 12 "laravel/framework": "^12.0"Use Laravel Shift (laravelshift.com) for automated upgrades — it handles most breaking changes automatically via a pull request.

3
Test thoroughly after upgrading
Run your full test suite and do manual QA:
php artisan test# Check for deprecation warnings php artisan test 2>&1 | grep -i deprecat# Verify critical paths - User registration and login - Payment processing - API endpoints - Background jobs - Email sendingDeploy to staging first and run smoke tests before production.
How to Verify
Verify your version is within the support window:
php artisan --versionCheck the Laravel release page at laravel.com/docs/releases for current support dates. Run php artisan stackshield:scan --check=SS055 to verify.
Prevention
Plan major version upgrades as part of your regular maintenance cycle. Budget for one major upgrade per year. Use Laravel Shift to automate the process. Subscribe to the Laravel blog for release announcements and security advisories.
Frequently Asked Questions
Can I skip major versions when upgrading?
Technically yes, but it is harder. Each major version introduces breaking changes. Skipping from 9 to 12 means dealing with three sets of breaking changes at once. Upgrade one major version at a time for the smoothest experience. Laravel Shift supports sequential upgrades.
What if I cannot upgrade due to a dependency?
Check if the dependency has a newer version compatible with your target Laravel version. If it is abandoned, find an alternative package. As a last resort, fork the dependency and update it. Do not let one outdated package keep your entire application on an unsupported framework.
What is the difference between a Laravel major version upgrade and updating Composer packages?
Updating a Composer package changes one library. Upgrading a major Laravel version changes the framework itself: how the application bootstraps, the middleware stack, service container behavior, routing conventions, and configuration file formats. Major upgrades require reviewing and applying breaking changes documented in the official upgrade guide, not just changing a version number.
What is Laravel Shift and when should I use it?
Laravel Shift (laravelshift.com) is a paid automated upgrade tool that opens a pull request with the mechanical changes required for a major version upgrade: updated composer.json constraints, renamed methods, changed signatures, updated configuration files, and adjusted middleware registration. Use it as the starting point for every major upgrade, then review and test the resulting PR carefully before merging.
Does the Laravel team ever backport security patches to end-of-life versions?
No. The official policy is that security fixes are only released for versions within the documented support window. If your application is on an end-of-life version and a critical CVE is published, the fix exists only in a supported version. Upgrading to a supported version is the only way to receive security fixes — the Laravel team does not release patches for EOL releases.
