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
SQL injection vulnerability in activerecord/lib/active_record/connection_adapters/postgresql/cast.rb in Active Record in Ruby on Rails 4.0.x before 4.0.3, and 4.1.0.beta1, when PostgreSQL is used, allows remote attackers to execute "add data" SQL commands via vectors involving \ (backslash) characters that are not properly handled in operations on array columns.

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 Active Record's PostgreSQL adapter (cast.rb) allows remote attackers to execute arbitrary SQL commands via backslash characters not properly escaped in array column operations. The vulnerability affects Rails 4.0.x before 4.0.3 and 4.1.0.beta1 when using PostgreSQL with array columns.

MitigationUpgrade Ruby on Rails to version 4.0.3 or later to receive the patch that properly escapes backslash characters in PostgreSQL array column operations.

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. Identify the installed Rails version
    Examine your Gemfile, Gemfile.lock, or run `rails --version` in your application directory to determine the Rails gem version
    Affected if The version is 4.0.0, 4.0.1, 4.0.2, or 4.1.0 (4.1.0.beta1)
  2. Confirm PostgreSQL is the active database adapter
    Inspect your config/database.yml file and check the adapter setting for your environment
    Affected if The adapter is set to 'postgresql'
  3. Verify the presence of PostgreSQL array columns
    Search your migration files for 't.array' column definitions or inspect your model files for array-type column declarations
    Affected if Your application uses array columns in PostgreSQL tables (PostgreSQL-specific feature)
  4. Inspect the vulnerable PostgreSQL adapter file
    Locate the cast.rb file in your Active Record PostgreSQL adapter directory (typically in activerecord/lib/active_record/connection_adapters/postgresql/) and check if the quote method properly escapes backslashes in array operations
    Affected if The code does not properly escape backslash characters in the array column quoting logic

You are affected if your Rails version is 4.0.0 through 4.0.2 or 4.1.0, you use PostgreSQL with array columns, and the vulnerable escape logic is present in your PostgreSQL adapter.
