Drupal has disclosed CVE-2026-9082, a highly critical SQL injection vulnerability (rated 20/25 on Drupal’s scale) in Drupal’s database abstraction API. The vulnerability allows attackers to send specially crafted requests to perform arbitrary SQL injection, potentially leading to information disclosure, privilege escalation, or remote code execution.
Important constraint: this vulnerability only affects sites using PostgreSQL as their database backend. However, all Drupal installations should update immediately due to critical upstream dependency fixes in Symfony and Twig included in the same release.
The vulnerability can be exploited by anonymous users with no authentication required. Drupal warns that exploits could be developed within hours or days of the public announcement.
Affected versions: Drupal 8.9.0 and later, Drupal 9.x (end-of-life, best-effort patch available), Drupal 10.4.0 through 10.6.x, and Drupal 11.0.0 through 11.3.x. Fixed in: 11.3.10, 11.2.12, 11.1.10, 10.6.9, 10.5.10, and 10.4.10.
