CVE-2026-9082 is an SQL Injection vulnerability in Drupal core caused by improper neutralization of special elements used in SQL commands. The flaw resides in the database abstraction layer where user-supplied input is concatenated into queries without proper parameterization. Specifically, certain Drupal core functions handling dynamic query conditions—such as those in the `Condition` class or during entity query parsing—fail to escape or bind values correctly when processing order by clauses or group by parameters. Attackers can inject malicious SQL fragments through unsanitized request parameters, for example via `$_GET` or `$_POST` data that end up in `db_select()` or `EntityQuery` calls. The vulnerability affects versions from 8.9.0 before 10.4.10, 10.5.0 before 10.5.10, 10.6.0 before 10.6.9, 11.0.0 before 11.1.10, 11.2.0 before 11.2.12, and 11.3.0 before 11.3.10. Exploitation allows an unauthenticated attacker to read, modify, or delete database contents, potentially leading to full site compromise. The issue stems from incomplete backporting of a security fix from later branches, leaving older versions exposed. Drupal’s database API uses `Database::getConnection()->query()` but certain helper methods bypass prepared statements. The CVE was published on May 20, 2026, and added to CISA’s Known Exploited Vulnerabilities catalog, indicating active exploitation. To trigger the injection, an attacker crafts a request with a specially designed sort parameter or filter condition that alters the SQL syntax, e.g., ?sort=field, (SELECT SLEEP(5)). Successful exploitation yields arbitrary SQL execution under the database user privileges.
dailycve form:
Platform: Drupal core 8.9-11.3
Version: All before fixed
Vulnerability: SQL Injection
Severity: Critical
date: 05/20/2026
Prediction: Expected by 05/27/2026
What Undercode Say:
Check current Drupal version via CLI
php core/scripts/drupal version
Update Drupal core using Composer to patched version
composer require drupal/core:10.4.10 --update-with-dependencies
For older branches, update accordingly:
composer require drupal/core:10.5.10
composer require drupal/core:10.6.9
composer require drupal/core:11.1.10
composer require drupal/core:11.2.12
composer require drupal/core:11.3.10
Verify database user privileges (should be least privilege)
mysql -u drupal_user -p -e "SHOW GRANTS;"
Quick audit for unsafe db_query() calls
grep -r "db_query(" web/modules/custom/
Exploit:
Craft a GET request to a vulnerable Drupal endpoint (e.g., `/admin/content` with sort parameter) containing a SQL payload: ?sort=, (SELECT UPDATEXML(1,CONCAT(0x7e,(SELECT @@version),0x7e),1)). Alternatively, use stacked queries if database supports it: ?filter=1; DROP TABLE users; --. Automated tools like sqlmap can detect the injection with --risk=3 --level=5.
Protection from this CVE
Immediately upgrade Drupal core to any fixed version (10.4.10, 10.5.10, 10.6.9, 11.1.10, 11.2.12, 11.3.10). If patching is delayed, deploy a Web Application Firewall (WAF) rule to block SQL keywords in query strings. Disable unauthenticated access to entity query endpoints via contributed modules like restrict_by_ip. Apply temporary patch using `git apply` if custom code is affected, and enforce prepared statements in any custom `db_query()` calls by replacing with `db_select()` and ->condition().
Impact:
Successful SQL injection allows an attacker to exfiltrate sensitive data (user hashes, session tokens, private content), escalate privileges by inserting admin accounts, bypass authentication, and execute denial-of-service via heavy queries. Database corruption or complete data loss is possible. As the CVE is known exploited, unpatched sites face imminent compromise.
