drupal-authentication-failures

A Drupal code-checking rule for finding weaknesses in how users are identified and logged in, such as weak password rules or unsafe custom authentication.

In plain words
What is it for?
Use it to review Drupal PHP, module, theme, install, and configuration files for password and login-related issues.
Why use it?
It helps catch authentication problems that could let attackers access accounts or bypass login checks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

drupal-authentication-failures scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Drupal Identification and Authentication Failures Standards (OWASP A07:2021)

This rule enforces security best practices to prevent identification and authentication failures in Drupal applications, as defined in OWASP Top 10:2021-A07.

Rule Details

  • Name: drupal_authentication_failures

  • Description: Detect and prevent identification and authentication failures in Drupal as defined in OWASP Top 10:2021-A07

Filters

  • file extension pattern: \\.(php|inc|module|install|theme|yml)$
  • file path pattern: .*

Enforcement Checks

  • Conditions:
    • pattern UserPasswordConstraint|PasswordPolicy|user\\.settings\\.yml – Ensure strong password policies are configured to require complexity, length, and prevent common passwords.
      • Pattern 1: Weak or missing password policies
    • pattern (authenticate|login|auth).*function[^}]*return\\s+(TRUE|true|1)\\s*; – Custom authentication functions should implement proper validation and not return TRUE without checks.
      • Pattern 2: Custom authentication without proper validation
    • pattern ==\\s*\\$password|===\\s*\\$password|strcmp\\(|password_verify\\([^,]+,[^,]+\\$plainTextPassword – Avoid direct password comparison. Use Drupal's built-in password verification services.
      • Pattern 3: Improper password comparison
    • pattern (username|user|pass|password|pwd)\\s*=\\s*['\"][^'\"]+['\"] – Hardcoded credentials detected. Store credentials securely outside of code.
      • Pattern 4: Credentials in code
    • pattern drupal_get_token\\(|form_token|\\$form\\[['\"]#token['\"]\\]\\s*=|drupal_valid_token\\( – Ensure proper CSRF protection is implemented for all authenticated actions.
      • Pattern 5: Missing or weak CSRF protection
    • pattern setcookie\\(|session_regenerate_id\\(false\\)|session_regenerate_id\\([^\\)]* – Use Drupal's session management. If custom code is required, ensure secure session handling practices.
      • Pattern 6: Insecure session management
    • pattern user\\.flood\\.yml|flood_control|UserFloodControl|user_failed_login_ – Ensure proper account lockout and flood control mechanisms are configured to prevent brute force attacks.
      • Pattern 7: Missing account lockout protection
    • pattern user_pass_reset|password_reset|reset.*token – Verify password reset functionality uses secure tokens with proper expiration and validation.
      • Pattern 8: Insecure password reset implementation
    • pattern tfa|two_factor|multi_factor|2fa – Consider implementing multi-factor authentication for sensitive operations or user roles.
      • Pattern 9: Lack of multi-factor authentication
    • pattern \\$user->name\\s*=\\s*['\"]admin['\"]|\\$name\\s*=\\s*['\"]admin['\"]|->values\\(['\"](mdc:name|mail)['\"]\\)\\s*->\\s*set\\(['\"][^\\'\"]+['\"]\\) – Avoid creating default administrator accounts or test users in production code.
      • Pattern 10: Default or test accounts

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

It costs nothing until one of its globs matches a file; then it loads 1,406 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
