• Brief description:
  • Have you ever wanted a fast way to catch the security mistakes that slip into custom Drupal code — especially the code your AI assistant just wrote — before it ships? There's a module for that.
• Module name/project name:
  • Security Scanner
• Brief history
  • How old: created in July 2026 by Mayank Gupta (mayankguptadotcom) of Acquia
  • Versions available: 1.0.0, which works with Drupal 10.3 and 11
• Maintainership
  • Actively maintained — created and shipped its first stable this summer, with steady development right through late July
  • Security coverage
  • Test coverage — and it's strong: unit and kernel tests, including a regression corpus built from real Drupal core advisories
  • Documentation? In-depth README with a full check table and CI recipes, plus a CHANGELOG
  • Number of open issues: 1 issue, not a bug
• Usage stats:
  • 2 sites (it's brand new)
• Module features and usage
  • Provide a Drush command, has no UI — you point drush security:scan at a module or any path, it reads the code statically, and prints a prioritized, OWASP-mapped list of things to review
  • It's built for the age of AI-written code — the checks target the classes AI assistants keep reintroducing: routes with no access check, #markup and |raw XSS, missing CSRF tokens, unserialize() on untrusted data, hardcoded secrets
  • Then there's an optional deep pass: with the Psalm static analysis scanning engine installed, it'll trace untrusted input across functions and files to catch cross-function issues. And it's honest about state — the report always says whether that deep pass ran, was skipped, or failed, so a failure never gets mistaken for a clean scan
  • One nice detail under the hood: a tokenizer-backed "code map" that knows whether a match is real code, a comment, or a string — so it won't flag the word "unserialize" sitting in a doc comment. That kills the single biggest source of false positives
  • The checks are regression-tested against real Drupal advisories (Drupalgeddon, Drupalgeddon2, the 2019 unserialize bug, etc) so a pattern that caused an actual CVE can't quietly come back in your custom code
  • Output comes in three flavors: a readable table, JSON for CI and AI agents, and SARIF — which means f
