CVE-2026-9082 Drupal Core PostgreSQL SQL Injection Overview and Takeaways
A critical vulnerability in Drupal Core, tracked as CVE-2026-9082, affects Drupal deployments using a PostgreSQL database.
The issue allows unauthenticated attackers to perform arbitrary SQL queries via crafted JSON:API or search queries. Successful exploitation may result in full database compromise or remote code execution.
If Drupal is running with a PostgreSQL backend, immediately upgrade to a patched version and ensure database permissions are properly restricted. Review logs and implement monitoring controls for SQL injection activity.
What do I need to know?
- CVE: CVE-2026-9082,
- Severity: Critical (CVSS 3.1: 9.8)
- Attack Vector: Remote, unauthenticated
- Root Cause: Improper neutralization of user-supplied array keys in PostgreSQL query filters
- Exposure Scope: Only Drupal deployments using PostgreSQL backend are affected
Products and Systems Affected
This issue affects the following Drupal Core versions:
- From 8.9.0 before 10.4.10
- From 10.5.0 before 10.5.10
- From 10.6.0 before 10.6.9

What do I need to do?
We recommend the following steps to identify and remediate this vulnerability:
Review and Audit
- Identify all Drupal environments using PostgreSQL
- Confirm current Drupal Core versions against affected ranges
- Review application and web logs for suspicious query parameters or injection patterns
- Look for use of PostgreSQL-specific functions or operators in inputs (e.g., pg_sleep, ::)
Patch Immediately
- Upgrade Drupal Core to the fixed versions listed above
Mitigation (If Patching Is Delayed)
- Restrict database permissions: ensure the PostgreSQL user does not have SUPERUSER rights
- Deploy WAF or IDS signatures for SQL injection detection
- Implement SIEM correlation rules focused on PostgreSQL exploitation behavior
- Increase monitoring for anomalous database queries and data access patterns
