Our experts conduct thorough penetration tests to detect and fix potential security vulnerabilities in your Drupal system. Through targeted analyses and realistic attack simulations, we improve the resilience of your websites against cyber threats.
What We Test in Drupal Projects
Code review for custom-developed modules, contrib modules and theme implementations for XSS, SQLi and access control.
Payment flows, checkout logic, order processing and PCI-DSS compliance in Commerce installations.
Role-based access control, content access modules, view permissions and field-level security.
Drupal is a modular enterprise CMS for data-driven applications - from complex news portals via intranet solutions to full-featured e-commerce platforms with Drupal Commerce. The flexibility comes at a price: custom modules, contrib code and complex permission systems regularly lead to critical vulnerabilities - from access control bypasses via SQL injections to configuration issues.
Custom Module Security We analyze custom-developed Drupal modules, contrib code and theme layer for classic web vulnerabilities (XSS, SQLi, CSRF) and Drupal-specific issues such as permission bypasses and entity access violations.
Drupal Commerce & Payment Security In Commerce installations we test payment flows, checkout logic, order manipulations and PCI-DSS-relevant controls - PII and financial data are highly attractive attack targets.
Configuration & Access Control Role-based access control, view permissions, field-level security and content access modules - we check granularly whether users can really only access authorized content.
We deliver prioritized results with code examples, concrete fix suggestions for your dev team and - if desired - management summaries for stakeholders and compliance audits.

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.
Drupal pentests uncover a wide spectrum of vulnerabilities - from classic PHP web vulnerabilities via Drupal-specific access control issues to configuration leaks.
Faulty permission checks in custom modules, misconfigured content access modules, view permission bypasses and entity access violations - Drupal's granular permission system is regularly implemented incorrectly.
Drupal's Database API is secure - but custom queries via db_query(), dynamic WHERE clauses and unsafe filter parameters in Views regularly lead to SQL injections. Especially in Commerce modules and search functions.
Despite Drupal's auto-escaping: Unsafe render arrays, direct HTML output via drupal_set_message(), custom Ajax callbacks without CSRF protection and missing #markup sanitization lead to XSS and CSRF.
Directory listing + .git/.env access, backup files in webroot, phpinfo() exposures, verbose error messages (Drupal debug mode) and unsafe settings.php permissions - classic info leaks that turn blackbox to whitebox.
Outdated or poorly maintained contrib modules with known CVEs, missing security updates, unsafe webform configurations and vulnerable admin panels in popular modules like Views, Panels, Webform.
User enumeration, weak default passwords for freelancer accounts, old admin accounts without MFA, unsafe password reset flows and known credentials from breach dumps - especially in agency projects.
With Drupal, the whitebox approach is almost always worthwhile - especially when custom modules or Commerce extensions are in use. We combine code review with dynamic testing.
We test without access to source code - like an external attacker. Focus is on configuration issues, contrib module vulnerabilities, information disclosure and access control bypasses. Limited for custom code, but effective for public-facing vulnerabilities.
Full access to source code, database and server config. We review custom modules, theme layer, Commerce extensions and hook implementations line by line. Combined with dynamic testing - maximum coverage for business-critical code.
The price depends on complexity - standard Drupal sites vs. Commerce installations with custom modules and payment integration make the difference.
For standard Drupal installations
For custom-heavy & Commerce projects
Our Mini Pentest for Drupal checks custom module vulnerabilities, permission bypasses, insecure views and configuration leaks. Ideal for content-heavy sites or news portals before major updates or go-live.
