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
An issue was discovered in Django 1.11.x before 1.11.23, 2.1.x before 2.1.11, and 2.2.x before 2.2.4. Due to an error in shallow key transformation, key and index lookups for django.contrib.postgres.fields.JSONField, and key lookups for django.contrib.postgres.fields.HStoreField, were subject to SQL injection. This could, for example, be exploited via crafted use of "OR 1=1" in a key or index name to return all records, using a suitably crafted dictionary, with dictionary expansion, as the **kwargs passed to the QuerySet.filter() function.

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 Django's PostgreSQL JSONField and HStoreField due to improper shallow key transformation. Attackers can inject arbitrary SQL via crafted key or index names in filter() queries using dictionary expansion, potentially returning all records through 'OR 1=1' type payloads.

MitigationUpgrade Django to version 1.11.23+, 2.1.11+, or 2.2.4+ to patch the vulnerability. If immediate upgrade is not possible, avoid passing user-controlled input as keys in JSONField/HStoreField filter() calls.

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.

  1. Check Django version
    Run 'python -c import django; print(django.get_version())' or check the installed package version via pip
    Affected if The installed version is >=1.11 and <1.11.23, or >=2.1 and <2.1.11, or >=2.2 and <2.2.4
  2. Confirm PostgreSQL backend in use
    Inspect settings.py and verify the DATABASESENGINE setting is set to 'django.db.backends.postgresql'
    Affected if PostgreSQL backend is used with Django versions in the affected ranges
  3. Identify JSONField or HStoreField usage
    Search codebase for imports and model definitions containing 'JSONField' or 'HStoreField' from 'django.contrib.postgres.fields'
    Affected if Codebase contains Django model fields using JSONField or HStoreField from django.contrib.postgres
  4. Find filter() with dictionary expansion
    Search code for filter(** variable patterns, particularly where user-supplied dictionaries are unpacked into filter() calls
    Affected if Application code passes dictionary expansion to filter() on models containing JSONField or HStoreField, especially with untrusted input

A system is affected if it runs a vulnerable Django version (1.11.x <1.11.23, 2.1.x <2.1.11, or 2.2.x <2.2.4) with PostgreSQL and uses JSONField or HStoreField with dictionary expansion in filter() calls where keys could be user-controlled.

Upgrade available Upgrade to 1.11.23 / 2.1.11 / 2.2.4 or later
Fixed in 1.11.232.1.112.2.4
Interim mitigation

Upgrade Django to version 1.11.23+, 2.1.11+, or 2.2.4+ to patch the vulnerability. If immediate upgrade is not possible, avoid passing user-controlled input as keys in JSONField/HStoreField filter() calls.

Recommended fix High confidence

Django 1.11.23, 2.1.11, or 2.2.4 (select based on your current major.minor version)

  1. 1. Identify your current Django version by running 'python -c "import django; print(django.get_version())"'
  2. 2. Determine which Django branch you are on (1.11.x, 2.1.x, or 2.2.x)
  3. 3. Upgrade Django to the corresponding fixed version: pip install --upgrade Django==1.11.23 (for 1.11.x), Django==2.1.11 (for 2.1.x), or Django==2.2.4 (for 2.2.x)
  4. 4. Verify the upgrade was successful: python -c "import django; print(django.get_version())"
  5. 5. Run your application's test suite to verify functionality
  6. 6. Deploy to production environment
Caveat Django patch releases are generally backward compatible; review the release notes for your specific version for any deprecation warnings or small behavioral changes
