CVE-2026-9082: Drupal Core SQL Injection Vulnerability

A SQL injection vulnerability in Drupal Core could let an attacker escalate privileges or execute code on the server by sending specially crafted requests through the database abstraction API. The issue is tracked as CVE-2026-9082 and stems from improper handling of input in database queries.

How it works

The weakness is classified as CWE-89, improper neutralization of special elements in an SQL command. An attacker supplies crafted input that reaches the database layer through the abstraction API, altering the intended query structure. This can result in unauthorized data access, privilege changes, or execution of server-side commands depending on database permissions and configuration.

Am I affected? How to find it in your systems

Inventory all Drupal Core installations across web servers, containers, and hosting environments. Review installed modules and custom code that interacts directly with the database abstraction layer. Examine configuration files and query patterns for unparameterized or dynamically built statements. No public exploit details are provided, so confirm exact affected versions and configurations against the vendor advisory. Look for unusual database error logs or unexpected query patterns that may indicate attempted abuse.

How to remediate

Apply the vendor-supplied update referenced in the official advisory as the primary step. After patching, review all database calls in custom modules for proper parameterization and input handling consistent with Drupal Core secure coding practices. Restrict database user privileges to the minimum required for application operation.

If you can't patch immediately

• Segment Drupal instances behind network controls that limit direct database access from untrusted sources.
• Deploy web application firewall rules that inspect and block anomalous request patterns targeting database endpoints.
• Disable or restrict any non-essential features that expose the database abstraction API to external input.
• Enable detailed logging of database queries and monitor for indicators of injection attempts until the update can be applied.
• Follow applicable CISA guidance for cloud-hosted instances or discontinue use if mitigations cannot be implemented.
