Summary: A highly critical SQL injection vulnerability affecting Drupal core is being actively targeted in the wild. Tracked as CVE-2026-9082, the vulnerability affects Drupal’s database abstraction API and could allow an unauthenticated remote attacker to execute arbitrary SQL injection against websites using PostgreSQL databases. Successful exploitation could result in information disclosure, privilege escalation, remote code execution, or other malicious activity. Drupal assigned the vulnerability a “highly critical” risk score of 23 out of 25.
Analyst Comment: Drupal is commonly used to support public-facing websites, customer portals, payment systems, and communications infrastructure, making it directly applicable to water and wastewater utilities using this platform.
Drupal confirmed exploitation attempts are now being detected in the wild and strongly encourages organizations to update affected systems immediately.
Affected Drupal core versions:
- Drupal 8.9.0 to 10.4.9
- Drupal 10.5.0 to 10.5.9
- Drupal 10.6.0 to 10.6.8
- Drupal 11.0.0 to 11.1.9
- Drupal 11.2.0 to 11.2.11

Drupal patched the vulnerability in versions 11.3.10, 11.2.12, 11.1.10, 10.6.9, and 10.4.10.
Although the SQL injection vulnerability specifically affects PostgresSQL-backed environments, Drupal noted the latest releases also include important security updates regardless of database configuration.
WaterISAC strongly encourages members review Drupal’s advisory, validate whether affected systems are internet accessible, identify whether PostgreSQL is in use, and upgrade affected Drupal instances to a patched version immediately.
