Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · unedited
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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidence
SQL injection vulnerability in Drupal core allows attackers to inject malicious SQL commands through unsanitized input fields, potentially enabling unauthorized database access, data theft, or complete system compromise.
MitigationUpgrade Drupal core to versions 10.4.10, 10.5.10, 10.6.9, 11.1.10, 11.2.12, or 11.3.10 or later to patch the SQL injection vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checks
Work through these to decide whether this CVE applies to you.
Identify installed Drupal core version
Check the composer.json file in your Drupal root directory for the 'drupal/core' version entry, or run 'drush status' and look for the Drupal version field, or inspect core/lib/Drupal.php for the VERSION constant
Affected if The version is >= 8.9.0 and < 10.4.10; or >= 10.5.0 and < 10.5.10; or >= 10.6.0 and < 10.6.9; or >= 11.0.0 and < 11.1.10; or >= 11.2.0 and < 11.2.12; or >= 11.3.0 and < 11.3.10
Locate publicly accessible forms or endpoints
Review your site's routing.yml files in modules and the core directory to identify routes with no authentication requirement that accept user input via query parameters or POST data
Affected if Publicly accessible forms or endpoints that process user-supplied input are present on the site
Check for custom modules handling database queries
Examine any custom or contributed modules in your modules/custom or modules/contributed directories for code that builds SQL queries using user input without using Drupal's database abstraction layer with proper placeholder handling
Affected if Custom modules contain direct database queries that incorporate unsanitized user input
Inspect database query logging
Enable database logging temporarily (via Drupal configuration or database settings) and review query logs for any suspicious or malformed SQL patterns originating from web requests
Affected if Unexpected or malformed SQL queries appear in logs with patterns suggesting injection attempts
You are affected if your Drupal core version falls within any of the vulnerable version ranges listed and your site exposes forms or endpoints that accept unauthenticated user input.
Generated from the published advisory. Verify against your own configuration.

Upgrade availableUpgrade to 10.4.10 / 10.5.10 / 10.6.9 or later
Upgrade Drupal core to versions 10.4.10, 10.5.10, 10.6.9, 11.1.10, 11.2.12, or 11.3.10 or later to patch the SQL injection vulnerability.
Recommended fixHigh confidence
Upgrade to Drupal 10.4.10+, 10.5.10+, 10.6.9+, 11.1.10+, 11.2.12+, or 11.3.10+ depending on your current major version branch
1. Back up your entire Drupal installation including the database and files.
2. Put your site in maintenance mode via /admin/config/development/maintenance or drush state-set system.maintenance_mode 1.
3. Update Drupal core using your preferred method (Composer, Drush, or manual upload): composer update drupal/core --with-all-dependencies
4. Clear the Drupal cache: drush cr or php core/scripts/drupal cache-clear.
5. Run database updates: drush updatedb or php core/scripts/drupal update-db.
6. Verify the update by checking the version at /admin/reports/status or drush core:status.
7. Take the site out of maintenance mode: drush state-set system.maintenance_mode 0.
Caveat Minor version upgrades within the same major branch (e.g., 10.6.x to 10.6.9) typically have no breaking changes; major version jumps may require module/theme compatibility review

CVE-2026-9082 is a SQL injection vulnerability in Drupal core that has persisted across seven years and versions 8.9 through 11.3. If you maintain any Drupal installation, treat this as incident response, not routine patching.
The seven-year persistence is the real story. This vulnerability survived the 8.x end-of-life, the entire 9.x lifecycle, and migrated into 10.x and 11.x. That's not a single missed sanitization — it's a code path that survived multiple architectural reviews, security audits, and major version transitions. The question you should be asking isn't just 'am I patched?' but 'what other legacy query patterns in my current version haven't been audited the same way?'
The simultaneous existence of separate patches for 10.4.x, 10.5.x, 10.6.x, 11.1.x, 11.2.x, and 11.3.x tells us something important about the codebase state. A vulnerability requiring divergent fixes across six active branches indicates either the vulnerable pattern was replicated by multiple developers across parallel tracks, or the fix required architectural changes that couldn't be uniformly propagated. Either interpretation suggests the blast radius of any database-layer change in Drupal is larger than the project admits.
With an EPSS score of 0.88319, this has one of the highest exploitation probability metrics recorded for a CMS vulnerability. Combined with CISA KEV confirmation of active exploitation, the disclosure-to-mass-exploitation window was effectively zero.
If you're on Drupal 9.x: those versions are unpatched and end-of-life. No fix is coming. Those installations are now permanently compromised infrastructure — not a risk to be managed with compensating controls, but infrastructure that should be taken offline. WAF rules catch known patterns but not novel payloads. Network isolation limits blast radius but doesn't remediate a fundamentally compromised application. The honest answer is that Drupal 9.x systems are now training infrastructure for attackers who will refine exploits against them before deploying against hardened 10.x and 11.x targets.
