Our specialized penetration tests scrutinize your Symfony applications down to the smallest detail. By conducting targeted attacks, we identify vulnerabilities.
What we test in Symfony projects
Security Voters, Guard Authenticators, Firewall configurations and Custom Authentication Providers for bypasses.
Server-Side Template Injections, unsafe filter usage, raw output and custom extensions for RCE potential.
DQL injections, QueryBuilder bypasses, mass assignment and API Platform serialization issues.
Symfony is the leading enterprise PHP framework for complex web applications and APIs - highly flexible, component-based and perfect for SaaS platforms. But this flexibility comes at a price: Server-Side Template Injections in Twig, Security Voter bypasses, Doctrine ORM misuse, .env file exposures and vulnerable bundles regularly lead to critical vulnerabilities - from SSTI-RCE to authorization bypasses to full database dumps via DQL injections.
Twig SSTI & Remote Code Execution Server-Side Template Injections in Twig templates - especially in email templates, custom filters and dynamically loaded templates - regularly lead to RCE. Twig is powerful, but unsafe usage is dangerous.
Security Voters & Authorization Bypasses Custom Security Voters, misconfigured firewalls, Guard Authenticator bypasses and access control issues in Symfony's Security Component - authorization logic is complex and error-prone.
Doctrine ORM & DQL Injections DQL injections in custom queries, QueryBuilder bypasses, mass assignment vulnerabilities and unsafe entity hydration - Doctrine is not automatically injection-safe.
We deliver prioritized results with PoC code, concrete fix recommendations for your dev team and - if desired - management summaries for stakeholders and compliance audits.

Your data will be treated confidentially and will not be passed on to third parties.
A large part of the internet is based on websites and web applications.
Modern websites and SPAs usually communicate with some kind of API.
Fully automated vulnerability scanning for your IT infrastructure or application.
Symfony pentests uncover a broad spectrum of vulnerabilities - from Twig SSTI to Security Voter bypasses to Doctrine injections, API Platform issues and OWASP Top 10.
Server-Side Template Injections in Twig - especially in email templates, custom filters and dynamically loaded templates. {{ user_input|raw }}, unsafe sandbox() and custom extensions lead to RCE.
Misconfigured firewalls, custom Security Voter bypasses, Guard Authenticator issues and access control errors in @IsGranted() - Symfony's Security Component is powerful, but complex.
DQL injections in custom queries, unsafe QueryBuilder usage with user input, mass assignment vulnerabilities in entity hydration and ORM query bypasses - Doctrine is not automatically secure.
Unsafe serialization groups, missing denormalizationContext protection, mass assignment via POST/PUT and authorization bypasses in custom operations - API Platform often exposes too much.
Exposed .env files, debug mode in production (APP_ENV=dev), verbose error messages and Symfony Profiler access - configuration issues reveal credentials and infrastructure details.
XSS despite Twig auto-escaping (via raw filter), missing CSRF protection in custom forms and vulnerable third-party bundles - the bundle ecosystem is large, but not always secure.
The price depends on complexity - simple REST APIs vs. enterprise SaaS platforms with API Platform, multi-tenancy and complex Security Voters make the difference.
