Unauthenticated SQL injection via database abstraction API
Published May 20, 2026 · Updated May 20, 2026
SQL injection in affected Drupal core releases allows remote attackers to execute arbitrary SQL through crafted requests. The PostgreSQL database abstraction API fails to sanitize a specially crafted request before incorporating attacker-controlled elements into an SQL query; Drupal has not disclosed the exact faulty method. Anonymous access is sufficient, but only sites using PostgreSQL are exposed; successful attacks can disclose or alter data and can escalate to code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=10.5.0 <10.5.10
