Drupal Core SQL Injection Bug Actively Exploited, Added to CISA KEV
Ravie LakshmananMay 23, 2026Vulnerability / Website Security
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a recently patched critical security flaw impacting Drupal Core to its Known Exploited Vulnerabilities (KEV) catalog, based on evidence of active exploitation.
The vulnerability in question is CVE-2026-9082 (CVSS score: 6.5), an SQL injection vulnerability affecting all supported versions of Drupal Core.
"Drupal Core contains a SQL injection vulnerability that could allow for privilege escalation and remote code execution via specially crafted requests sent with the database abstraction API," CISA said.
News of exploitation arrives less than two days after Drupal released fixes for the flaw. Patches are available for the following versions -
Drupal 11.3.10 Drupal 11.2.12 Drupal 11.1.10 Drupal 10.6.9 Drupal 10.5.10 Drupal 10.4.10 Drupal 9.5 (Manual patching required) Drupal 8.9 (Manual patching required)
In an update to its advisory on May 22, 2026, Drupal acknowledged that "exploit attempts are now being detected in the wild." Thales-owned Imperva said it has observed over 15,000 attack attempts targeting almost 6,000 individual sites across 65 countries.
"Attacks are primarily targeting gaming and financial services sites so far, at collectively almost 50% of all attacks," the company said. "Most of the observed activity so far appears to be probing."
"This pattern suggests attackers and scanners are primarily attempting to identify exposed Drupal sites running vulnerable PostgreSQL-backed configurations. While the activity is currently dominated by reconnaissance and validation, the nature of the vulnerability means successful exploitation could quickly move from probing to data extraction or privilege escalation."
Federal Civilian Executive Branch (FCEB) agencies have been recommended to apply the fixes by May 27, 2026, for optimal protection.
