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 confidenceMissing Authorization vulnerability in ThemeFusion Fusion Builder allows attackers to exploit incorrectly configured access control security levels. The vulnerability stems from improper access control checks that fail to properly validate user permissions before allowing access to sensitive functionality. This enables unauthorized users to potentially access or manipulate builder features that should require elevated privileges.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify Fusion Builder is installedLocate the Fusion Builder plugin or theme in your WordPress installation. Check the plugin/theme directory for 'fusion-builder' or 'ThemeFusion' components, or view the installed plugins in WordPress admin.Affected if Fusion Builder is present in the environment
-
Determine installed Fusion Builder versionAccess the WordPress admin dashboard, navigate to Plugins > Installed Plugins, and locate Fusion Builder to view its current version number. Alternatively, check the version in the theme/plugin header files if accessible via file system.Affected if Version cannot be determined or is visible in the plugin listing
-
Compare version against patched releaseCompare the installed version number to 3.15.0. Any version lower than 3.15.0 contains the vulnerability.Affected if Installed version is earlier than 3.15.0 (e.g., 3.14.x, 3.13.x, etc.)
-
Inspect Fusion Builder access control settingsIn WordPress admin, go to Fusion Builder settings or Theme Options > User Access. Review the access control security levels configured for builder features, particularly any custom role or capability configurations.Affected if Access control settings allow lower-privilege users (subscribers, contributors, or unauthenticated users) to access builder features that should require admin or editor privileges
Environment is affected if Fusion Builder is installed with a version earlier than 3.15.0 and has access control configurations that permit unauthorized users to access builder functionality.

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 · scopedUpgrade Fusion Builder to version 3.15.0 or later to obtain the patched access control configuration. Review user role capabilities and ensure the principle of least privilege is applied to any custom access configurations.
Fusion Builder 3.15.0 or later
- 1. Backup your WordPress site and database before making any changes
- 2. Identify the current version of Fusion Builder installed on your WordPress site
- 3. Navigate to the WordPress admin dashboard
- 4. Go to Plugins > Installed Plugins
