Latest Drupal core vulnerability: CVE-2026-9082 #

Drupal disclosed that certain versions of Drupal core are affected by a SQL injection vulnerability in the database abstraction API due to the improper neutralization of special elements. This flaw allows a remote, unauthenticated attacker to send specially crafted requests that result in arbitrary SQL execution on sites configured to use a PostgreSQL database. Successful exploitation allows an attacker to achieve information disclosure and, in select cases, privilege escalation, remote code execution (RCE), or other attacks. This vulnerability has been designated CVE-2026-9082 and has been rated critical with a CVSS score of 9.8.

There is evidence that this vulnerability is being actively exploited in the wild.

    The following versions are affected:

    • Drupal: Versions 8.9.0 to before 10.4.10
    • Drupal: Versions 10.5.0 to before 10.5.10
    • Drupal: Versions 10.6.0 to before 10.6.9
    • Drupal: Versions 11.0.0 to before 11.1.10
    • Drupal: Versions 11.2.0 to before 11.2.12
    • Drupal: Versions 11.3.0 to before 11.3.10

    Note: this vulnerability only affects sites configured to use a PostgreSQL database.
