drupal-logging-failures

A Drupal code rule that checks whether security-relevant actions and errors are properly recorded and monitored, based on the OWASP Top 10.

In plain words
What is it for?
Use it to review Drupal code for missing logs around operations such as deleting, updating, granting access, or changing configuration, as well as suppressed errors and unlogged exceptions.
Why use it?
It helps prevent important actions from happening without an audit trail and highlights code that hides errors instead of recording them.

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-logging-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 Security Logging and Monitoring Failures Standards (OWASP A09:2021)

This rule enforces security best practices to prevent logging and monitoring failures in Drupal applications, as defined in OWASP Top 10:2021-A09.

Rule Details

  • Name: drupal_logging_failures

  • Description: Detect and prevent security logging and monitoring failures in Drupal as defined in OWASP Top 10:2021-A09

Filters

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

Enforcement Checks

  • Conditions:
    • pattern (delete|update|create|execute|grant|revoke|config|schema).*function[^}]*\\{(?![^}]*(log|watchdog|logger)) – Critical operations should include logging. Implement proper logging for security-relevant actions.
      • Pattern 1: Missing critical event logging
    • pattern @include|@require|@eval|error_reporting\\(0\\)|ini_set\\(['\"](mdc:display_errors|log_errors)['\"],\\s*['\"]0['\"]\\) – Avoid suppressing errors and warnings. Implement proper error handling and logging instead.
      • Pattern 2: Suppressed error logging
    • pattern catch\\s*\\([^{]*\\)\\s*\\{(?![^}]*log|[^}]*watchdog|[^}]*logger) – Exceptions should be properly logged, especially in security-critical sections.
      • Pattern 3: Improper exception handling without logging
    • pattern dblog\\.settings\\.yml|syslog\\.settings\\.yml|logging\\.settings\\.yml – Ensure logging is properly configured and not disabled. Verify log verbosity and retention policies.
      • Pattern 4: Disabled watchdog
    • pattern (login|authenticate|logout|password).*function[^}]*\\{(?![^}]*(log|watchdog|logger)) – Authentication events should always be logged for security monitoring and auditing.
      • Pattern 5: Missing authentication event logging
    • pattern AccessResult::(allowed|forbidden|neutral)\\([^)]*\\)(?![^;]*(log|watchdog|logger)) – Consider logging significant access control decisions, especially denials, for security monitoring.
      • Pattern 6: Failure to log access control decisions
    • pattern (file_save|file_delete|file_move|file_copy)[^;]*;(?![^;]*(log|watchdog|logger)) – File operations should be logged, especially for security-sensitive files.
      • Pattern 7: Missing logging in file operations
    • pattern (\\->log|watchdog)\\([^,)]*,[^,)]*\\) – Log messages should include sufficient context and detail for effective security monitoring.
      • Pattern 8: Insufficient detail in log messages
    • pattern \\$config->set\\([^;]*;(?![^;]*(log|watchdog|logger)) – Configuration changes should be logged to maintain an audit trail and detect unauthorized changes.
      • Pattern 9: Failure to log configuration changes
    • pattern class\\s+[a-zA-Z0-9_]+Resource.+\\{[^}]*function\\s+[a-zA-Z0-9_]+\\([^{]*\\)\\s*\\{(?![^}]*(log|watchdog|logger)) – API endpoint access should be logged for security monitoring, especially for sensitive operations.
      • Pattern 10: Missing logs for API access

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.

drupal-logging-failures is a cursor rule published in the GitHub repository ivangrynenko/cursorrules (87 stars, last pushed 10mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,494 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.
