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
The findByCondition function in framework/db/ActiveRecord.php in Yii 2.x before 2.0.15 allows remote attackers to conduct SQL injection attacks via a findOne() or findAll() call, unless a developer recognizes an undocumented need to sanitize array input.

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

The findByCondition function in Yii 2.x ActiveRecord.php before 2.0.15 fails to properly sanitize array keys passed to findOne() and findAll() methods, allowing unauthenticated remote attackers to inject arbitrary SQL commands through unsanitized array input.

MitigationUpgrade Yii 2.x to version 2.0.15 or later which patches the findByCondition function; alternatively, manually validate and sanitize all array parameters passed to findOne()/findAll() until the upgrade is completed.

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. Determine Yii 2.x framework version
    Locate the Yii version file (typically vendor/yiisoft/yii2/VERSION or composer.lock) and read the installed version number
    Affected if version is 2.0.0 or higher but below 2.0.15
  2. Identify ActiveRecord model usage
    Search codebase for classes extending yii\db\ActiveRecord that implement findOne() or findAll() methods with array arguments
    Affected if ActiveRecord models use findOne() or findAll() with array parameters
  3. Trace array input source to findByCondition
    Review code paths where user-supplied data (GET/POST parameters, JSON input) flows into array keys passed to findOne() or findAll()
    Affected if unsanitized user input directly populates array keys passed to these finder methods
  4. Inspect ActiveRecord.php findByCondition function
    Examine vendor/yiisoft/yii2/db/ActiveRecord.php and locate the findByCondition method; verify if array keys are sanitized before SQL construction
    Affected if the function does not sanitize array keys and user-controlled arrays can reach this method

You are affected if your Yii 2.x version is below 2.0.15 and your application passes unsanitized user-supplied array keys to findOne() or findAll() methods in ActiveRecord models.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade available Upgrade to 2.0.15 or later
Fixed in 2.0.15
Interim mitigation

Upgrade Yii 2.x to version 2.0.15 or later which patches the findByCondition function; alternatively, manually validate and sanitize all array parameters passed to findOne()/findAll() until the upgrade is completed.

Recommended fix High confidence

Yii 2.0.15 or later

  1. Check current Yii version in composer.json or run 'composer show yiisoft/yii2'
  2. Update Yii framework to version 2.0.15 or later: composer require yiisoft/yii2:^2.0.15 or composer update yiisoft/yii2
  3. Verify the upgrade was successful by checking the installed version
  4. Run application tests to ensure functionality remains intact after the upgrade
Caveat Review Yii 2.0.15 release notes for any breaking changes or deprecation notices specific to your version
