Csrf Protector Php Laravel Package
owasp/csrf-protector-php
OWASP CSRF Protector for PHP helps defend web apps against cross-site request forgery using token generation, validation, and configurable per-session or per-form protection. It integrates into existing PHP projects to secure state-changing requests.
OWASP CSRF Protector PHP is a lightweight library for adding Cross-Site Request Forgery protection to PHP applications. It generates and validates anti-CSRF tokens, helping secure forms, AJAX requests, and state-changing endpoints against forged requests.
- Token generation and validation for forms and requests
- Session-backed CSRF protection with configurable token names
- Support for multiple tokens and per-form usage
- Easy integration into existing PHP applications
- Configurable logging and blocking behavior
Frequently asked questions about Csrf Protector Php
- Is owasp/csrf-protector-php compatible with Laravel?
- It can be made to work, but it is not an idiomatic Laravel package. The library is a standalone, session-oriented PHP CSRF implementation with no Laravel service provider, middleware, facade, or maintained adapter. Laravel already owns CSRF protection through VerifyCsrfToken, Blade @csrf, and the XSRF-TOKEN cookie, so adding this package creates duplicate token systems. Use it only as a tactical bridge for legacy routes that cannot yet use native Laravel CSRF.
- How do I install and configure owasp/csrf-protector-php in a Laravel app?
- You can require the package with Composer, but installation alone does not give you Laravel integration. You would need custom bootstrap or middleware glue, route scoping, token wiring for Blade and AJAX clients, and mapping of library failures to Laravel responses. Avoid applying it globally alongside VerifyCsrfToken; scope any proof of concept to a low-risk legacy route and document rollback.
- Does owasp/csrf-protector-php provide a Laravel service provider or middleware?
- No. The supplied metadata describes a standalone PHP library with procedural bootstrap and configuration patterns, not a Laravel-native package. Any middleware, facade, or adapter would be custom code your team owns. The lack of a maintained Laravel wrapper and low ecosystem adoption makes this a high-ownership integration.
- Why should Laravel developers use native CSRF instead of this package?
- Laravel's VerifyCsrfToken middleware, Blade @csrf directive, XSRF-TOKEN cookie, and SPA-friendly behavior are framework-native and actively maintained with Laravel. They avoid duplicate token systems, conflicting validation paths, and custom glue for a security control Laravel already provides. For a modern Laravel application, native CSRF should be the default and this package should not be added.
- Can owasp/csrf-protector-php handle AJAX, SPA, and multipart forms in Laravel?
- The library advertises form and AJAX support, but the supplied metadata does not confirm SPA behavior, multipart upload handling, or token rotation details. A Laravel integration would need custom mapping between the library's AJAX header conventions and your JavaScript clients. For SPAs and stateless APIs, Laravel's XSRF-TOKEN cookie and session model are usually a better fit. Validate every required case in a spike before relying on it.
- What PHP and Laravel versions does owasp/csrf-protector-php support?
- The supplied metadata does not specify supported PHP or Laravel versions. The last release was 2020-05-23, so PHP 8+ compatibility and behavior on current Laravel session drivers are uncertain. Run a compatibility spike against your exact PHP, Laravel, and session storage stack before production use.
- How should I test an owasp/csrf-protector-php integration in Laravel?
- Test that forged state-changing requests are rejected and valid tokens are accepted on the scoped routes. Add feature tests for AJAX headers, multipart forms, token rotation, session drivers, and failure responses mapped through Laravel. During migration, test legacy and native Laravel routes separately so duplicate CSRF systems do not create confusing false negatives.
- Is owasp/csrf-protector-php maintained and safe for production?
- The package shows a last release in 2020, zero dependents, and no demonstrated active security disclosure or CVE response process in the supplied metadata. For a security-critical dependency, that implies high ownership risk and a likely need to fork, patch, and retest on PHP and Laravel upgrades. Treat it as high risk and require security review before production, especially in a modern Laravel app.
- What license does owasp/csrf-protector-php use?
- GitHub reports NOASSERTION for the license, which means the license is not clearly identified by the repository metadata. Legal review is required before commercial distribution or production use. Do not assume OWASP branding grants a usable license for your organization.
- What are the alternatives to owasp/csrf-protector-php in Laravel, and how do I migrate?
- The primary alternative is Laravel's native CSRF protection using VerifyCsrfToken, Blade @csrf, and the XSRF-TOKEN cookie for JavaScript clients. If the package is needed for a legacy PHP perimeter, use it only on legacy routes and replace it route-by-route with native Laravel CSRF. Avoid a big-bang dual-CSRF rollout, wrap any bridge in a small internal adapter, and schedule removal.
