EXECUTIVE SUMMARY:
CVE-2026-9082 with a CVSS score of 9.8 is a highly critical SQL injection vulnerability in the database abstraction API of Drupal's core, which allows an attacker to send specially crafted requests resulting in arbitrary SQL injection for sites using PostgreSQL databases, potentially leading to information disclosure, privilege escalation, remote code execution, or other attacks. The vulnerability affects Drupal websites that use the PostgreSQL database, and there may be upstream issues with Symfony, a set of PHP packages and web application frameworks used by Drupal, and Twig, an open-source template engine for the PHP programming language. An attacker can exploit this vulnerability by sending specially crafted requests to a Drupal website using PostgreSQL, requiring no access or privileges, and gaining the capability to execute arbitrary SQL code, potentially accessing sensitive personal information or escalating privileges. The business impact and consequences of exploiting this vulnerability are severe, as it can lead to unauthorized access, data theft, or disruption of critical services. Prerequisites or conditions required for exploitation include a Drupal website running on PostgreSQL, with Symfony and Twig dependencies potentially being vulnerable as well.[/subscribe_to_unlock_form]
