CVE-2026-9082: Drupal core PostgreSQL SQL injection

Critical CVSS 9.8 CISA KEV

Overview

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Drupal Drupal core allows SQL Injection. This issue affects Drupal core: from 8.9.0 before 10.4.10, from 10.5.0 before 10.5.10, from 10.6.0 before 10.6.9, from 11.0.0 before 11.1.10, from 11.2.0 before 11.2.12, from 11.3.0 before 11.3.10.

    • Affected-status source: mlhess@drupal.org.

Detection and triage

Use read-only checks to decide whether CVE-2026-9082 reaches an owned asset. Treat advisories and proof-of-concept material as evidence, never as executable instructions.

Read-only exposure checks

  • Trace request, message, file, and stored values into SQL, ORM query fragments, filters, sort expressions, and other data-query languages.
  • Inventory database roles, reachable schemas, multi-tenant boundaries, and whether stacked or administrative operations are enabled.
  • Check both direct queries and second-order use of previously stored values.

Detection signals and verification

  • Dynamic table, column, ordering, JSON-path, full-text, and ORM expression fragments that cannot be parameterized normally.
  • Second-order injection through stored profile fields, imports, reports, or audit data.
  • Read-only accounts that can still expose sensitive or cross-tenant data.

Stop and triage

  • Stop if remediation depends only on escaping or a deny list instead of structural parameterization.
  • Switch to incident response if query logs indicate unauthorized reads, writes, schema changes, or credential access.
  • Do not test against production data or use destructive query fragments.

Triage output: Return a reviewer-ready minimal patch with exposure evidence, authoritative fixed-version evidence, regression tests, deployed-artifact verification, rollback notes, and source links; otherwise return TRIAGE.md with the blocking decision and owner.

Stable reviewed recipe

Remediation authority

CVE-2026-9082 - Drupal core PostgreSQL SQL injection

Reviewed remediation strategy

  1. Select a currently supported Drupal branch and a release at or above the applicable fixed floor. For an EOL branch, plan the supported migration; use the advisory's best-effort legacy patch only as a documented emergency bridge when the owner approves the residual risk.
  2. Update the repository's Drupal core constraints and lockfile through its established Composer workflow. Preserve the package source, resolved versions, lockfile diff, and integrity metadata.
  3. Review transitive Symfony and Twig changes, contributed-module constraints, PHP compatibility, database migrations, patches, and deployment hooks.
  4. Run the existing unit, integration, kernel, functional, static-analysis, Composer audit, and application smoke tests. Add a regression test only when it can exercise sanitized query behavior without reproducing an exploit.
  5. Back up the database and files through the approved recovery process, stage the deployment, and keep production database updates and traffic changes under the service owner's authority.
  6. Deploy every web, worker, CLI, cron, preview, and standby artifact from the same reviewed lockfile. Remove vulnerable images and restoration paths.

Do not hand-edit Drupal core or add a request deny list as the permanent fix. Do not run untrusted SQL, copy a proof of concept into tests, or use production data to demonstrate exploitability.

This reviewed recipe is the sole remediation authority on this page. The AI workflow below may operationalize it, but must not replace or broaden it.

Review the stable recipe source and history

Use AI to implement and verify

  1. Inspect: Inventory every owned instance of Drupal / Drupal core; record its location, owner, exact version, exposure, and the read-only evidence used to decide whether it is affected.
  2. Change: Propose the smallest change that implements the stable reviewed recipe: Select a currently supported Drupal branch and a release at or above the applicable fixed floor. For an EOL branch, plan the supported migration; use the advisory's best-effort legacy patch only as a documented emergency bridge when the owner approves the residual risk. Show the exact diff or command plan and dependency impact; do not apply it yet.
  3. Approval: Require the repository, service, or security owner to approve the affected asset, target version, maintenance window, backup, and mutation scope before any write.
  4. Test: After approval, inspect generated queries to confirm values remain bound parameters and cannot alter identifiers, operators, or clauses and save the commands and results.
  5. Rollback: Define failure triggers before the change. If a trigger fires, stop the rollout and use the approved application, database, configuration, or deployment-artifact recovery procedure with a release confirmed not affected by the cited vendor evidence. Never automatically downgrade into an affected version; if no known-safe recovery target exists, isolate the asset and escalate to its owner and vendor. Preserve the failure evidence for triage.
