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
Smarty before 3.0.0, when security is enabled, does not prevent access to the (1) dynamic and (2) private object members of an assigned object, which has unspecified impact and remote attack vectors.

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 · moderate confidence

Smarty before 3.0.0 has a security bypass vulnerability where, even with security mode enabled, the template engine fails to properly restrict access to dynamic and private object members of assigned objects. This allows remote attackers to potentially access restricted object properties through template variables.

MitigationUpgrade Smarty to version 3.0.0 or later where this security restriction is properly enforced. If immediate upgrade is not feasible, audit all template files for object assignments and ensure no sensitive objects are exposed to the template layer.

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 installed Smarty version
    Check your project's Smarty library version by locating the Smarty.class.php or similar core file and reading the version constant or changelog. Common locations: vendor/smarty/smarty/ or lib/Smarty/.
    Affected if The version is 3.0.0 or lower, specifically 1.0, 1.0a, 1.0b, 1.1.0, 1.2.0, 1.2.1, 1.2.2, 1.3.0, 1.3.1, 1.3.2, or 1.4.0.
  2. Verify Smarty security mode configuration
    Search your Smarty initialization code for $smarty->security = true; or $smarty->setSecurityEnabled(true); to determine if security mode is enabled.
    Affected if Security mode is enabled, but the vulnerability still exists in these versions regardless of this setting.
  3. Identify object assignments in PHP code
    Search your application source code for patterns like $smarty->assign($object) or $tpl->assign('varname', $object) where $object is a class instance.
    Affected if Your application assigns PHP objects to Smarty templates.
  4. Inspect templates for object property access
    Review .tpl template files for syntax like {$obj->property} or {$obj->dynamicProperty} to see if assigned objects are accessed within templates.
    Affected if Templates access properties of assigned objects, especially dynamic or private members that should be restricted.

Your environment is affected if you run Smarty version 3.0.0 or any of the listed 1.x versions and your application assigns objects to templates that are then accessed within the template layer.

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.

dbcve · scoped
Upgrade available Upgrade to a release after 3.0.0
Interim mitigation

Upgrade Smarty to version 3.0.0 or later where this security restriction is properly enforced. If immediate upgrade is not feasible, audit all template files for object assignments and ensure no sensitive objects are exposed to the template layer.

Recommended fix High confidence

Smarty 3.0.0 or later (recommended: latest stable 3.x release)

  1. 1. Identify the current Smarty version in use (check composer.json, include statements, or vendor directory)
  2. 2. Backup the current codebase
  3. 3. Update Smarty to version 3.0.0 or later (preferably the latest stable 3.x version for additional fixes)
  4. 4. Verify the new Smarty version is installed
  5. 5. Test application functionality to ensure the upgrade does not break existing templates
  6. 6. If using a package manager (Composer), run: composer require smarty/smarty:^3.1 (or appropriate version constraint)
Caveat Smarty 3.x has template syntax changes from Smarty 2.x; review Smarty 2→3 migration guide for breaking changes in template syntax and API
