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 · uneditedSubscriber Arbitrary Code Execution in Cornerstone < 7.8.8 versions.
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 confidenceA vulnerability in Cornerstone versions prior to 7.8.8 allows users with the Subscriber role to execute arbitrary code on the server, likely due to insufficient authorization checks on sensitive functions that should only be accessible to administrators.

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.
-
Determine the installed Cornerstone versionLocate the version information in your Cornerstone installation (typically found in the admin dashboard, about page, or version file). Compare this version number against the affected range (versions prior to 7.8.8).Affected if The installed version is lower than 7.8.8
-
Confirm the Subscriber role is activeAccess the user role management section of your Cornerstone admin panel and verify whether the Subscriber role exists and has active user accounts assigned to it.Affected if The Subscriber role is present and has at least one active user account
-
Verify authorization controls on sensitive functionsAttempt to access or invoke administrative functions (such as file management, code execution, or system configuration endpoints) using a test account with only the Subscriber role. Alternatively, review role permission configurations to confirm whether Subscriber role has been granted access to privileged operations.Affected if Subscriber role users can access or execute functions that should be restricted to administrator-level accounts
-
Check for unexpected code execution capabilitiesReview the permission settings or access control lists for the Subscriber role and identify whether any permissions allow uploading files, executing scripts, running commands, or modifying server-side content.Affected if Subscriber role has permissions to execute code, upload files, or run server-side scripts
You are affected if your Cornerstone installation is version 7.8.7 or earlier AND the Subscriber role has access to administrative or code-execution functions.

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 Cornerstone to version 7.8.8 or later to remediate the vulnerability.
7.8.8 or higher
- 1. Back up your WordPress site and database before making any changes.
- 2. Navigate to the WordPress admin dashboard > Plugins.
- 3. Locate the Cornerstone plugin in the installed plugins list.
- 4. If an update is available, click 'Update Now' to upgrade to version 7.8.8 or later.
- 5. Alternatively, manually download the latest version from the WordPress plugin repository or the official vendor site.
- 6. Deactivate and delete the old version if the automatic update does not work, then install the new version.
- 7. After updating, verify the plugin is running version 7.8.8 or higher under Plugins > Installed Plugins.
- 8. Test that the site functionality remains intact after the update.
