The Cybersecurity and Infrastructure Security Agency (CISA) has issued an urgent advisory warning organizations about a critical SQL injection vulnerability in Drupal Core, tracked as CVE-2026-9082.
The flaw has been added to CISA’s Known Exploited Vulnerabilities (KEV) catalog following confirmed active exploitation in the wild, raising significant concern for enterprises and government entities relying on Drupal-powered websites.
The vulnerability stems from improper handling of user-supplied input within Drupal Core’s database abstraction API. Classified under CWE-89 (SQL Injection), the flaw enables attackers to inject and execute malicious SQL queries through specially crafted HTTP requests and critically, this can be done without authentication, making it remotely exploitable with a low barrier to entry.
Successful exploitation could allow threat actors to:
- Escalate privileges within the affected system
- Access or exfiltrate sensitive database contents
- Potentially achieve remote code execution (RCE) on vulnerable hosts
| Detail | Information |
|---|---|
| CVE ID | CVE-2026-9082 |
| Affected Product | Drupal Core |
| Vulnerability Type | SQL Injection (CWE-89) |
| Impact | Privilege escalation, data exposure, potential RCE |
| Exploitation Status | Actively exploited in the wild |
| KEV Added | May 22, 2026 |
| Federal Remediation Deadline | May 27, 2026 |
CISA added CVE-2026-9082 to its KEV catalog on May 22, 2026, mandating that federal agencies remediate the vulnerability by May 27, 2026, under Binding Operational Directive (BOD) 22-01.
Under this directive, agencies must apply vendor-recommended mitigations or discontinue use of affected products if no fix is available. While no specific ransomware campaigns have been publicly attributed to this vulnerability yet, the active exploitation status signals imminent escalation risk.
Drupal powers a significant portion of enterprise and government websites globally, making the attack surface exceptionally broad.
The flaw is especially dangerous in environments where database access controls are inadequately configured or where web application firewalls (WAFs) lack proper SQL injection detection rules. Attackers exploiting CMS platforms like Drupal typically use them as an initial access vector before moving laterally through the network.
SQL injection remains one of the most consistently exploited vulnerability classes due to its operational simplicity and disproportionate impact a pattern that security teams cannot afford to underestimate.
Mitigation
Organizations running Drupal Core should take the following steps immediately:
- Apply the latest security patches from the Drupal security team without delay
- Review and harden database access controls and least-privilege configurations
- Deploy or update WAF rules specifically targeting SQL injection patterns
- Monitor server and database logs for anomalous query behavior or unusual access patterns
- Follow CISA BOD 22-01 remediation timelines if operating within federal or regulated environments
- If patching is not immediately feasible, restrict external access to affected services or temporarily take them offline
Security teams should treat CVE-2026-9082 as a critical priority and continuously monitor threat intelligence feeds for updated indicators of compromise and attribution as this campaign evolves.
