Drupal Core SQL Injection Vulnerability (CVE-2026-9082) Critical Security Advisory
Executive & SecOps Summary
SECOPS ASSESSMENTDrupal core versions 8.9.0 to < 10.4.10, 10.5.0 to < 10.5.10, 10.6.0 to < 10.6.9, 11.0.0 to < 11.1.10, 11.2.0 to < 11.2.12, and 11.3.0 to < 11.3.10
Unauthenticated remote attackers can inject malicious SQL queries to extract sensitive database information, hijack administrator sessions, or potentially achieve Remote Code Execution (RCE).
Immediately upgrade Drupal core to the respective patched versions (10.4.10, 10.5.10, 10.6.9, 11.1.10, 11.2.12, 11.3.10, or later).
Affected Products & Version Scope
Remediation & Live Workaround Commands
PATCH & WORKAROUND1. Apply Official Security Patches
Immediately upgrade your Drupal Core installation to a secure version using Composer.
- Composer Update Command:
# Update Drupal Core to the latest secure release
composer update drupal/core-recommended --with-dependencies2. Temporary Mitigations (Prior to Patching)
If immediate patching is not feasible, implement the following temporary controls:
- Deploy WAF Rules:
Configure your Web Application Firewall (WAF) to detect and block common SQL injection patterns (e.g., UNION SELECT, OR 1=1, and encoded SQL syntax).
# Example ModSecurity Rule
SecRule REQUEST_COOKIES|REQUEST_COOKIES_NAMES|REQUEST_HEADERS|REQUEST_LINE|REQUEST_URI|REQUEST_BODY "(?i)(union\s+all\s+select|select\s+.*\s+from|insert\s+into|update\s+.*\s+set)" \
"id:1000001,phase:2,deny,status:403,log,msg:'Potential SQL Injection Attempt'"- Database Privilege Minimization:
Ensure the database user account used by Drupal operates under the principle of least privilege, disabling administrative capabilities such as file system access (LOAD_FILE, SELECT ... INTO OUTFILE).
Block Exploits Instantly with Managed Virtual Patching Rules
Can't patch production immediately? Deploy managed WAF rules at the edge to intercept RCE, SQLi, and deserialization payloads before they hit your origin server.
Technical Root Cause & Exploitation Mechanics
This advisory addresses a critical SQL Injection vulnerability (CVE-2026-9082) in Drupal Core with a CVSS score of 9.8. The vulnerability stems from improper neutralization of special elements used in an SQL command (CWE-89) within the core database abstraction layer.
An unauthenticated remote attacker can exploit this flaw (AV:N/AC:L/PR:N/UI:N) by sending crafted HTTP requests containing malicious SQL payloads. Successful exploitation allows the attacker to read, modify, or delete arbitrary data within the database. Given Drupal's architecture, manipulating database tables (such as sessions or configuration) can lead to administrative privilege escalation and full Remote Code Execution (RCE).
This vulnerability is actively exploited in the wild and is listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, with an EPSS score of 0.94, requiring immediate remediation.
Official Vendor Advisories & References
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Drupal Drupal core allows SQL Injection. This issue affects Drupal core: from 8.9.0 before 10.4.10, from 10.5.0 before 10.5.10, from 10.6.0 before 10.6.9, from 11.0.0 before 11.1.10, from 11.2.0 before 11.2.12, from 11.3.0 before 11.3.10.
