CVE-2024-3027
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 · uneditedThe Smart Slider 3 plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the upload function in all versions up to, and including, 3.5.1.22. This makes it possible for authenticated attackers, with contributor-level access and above, to upload files, including SVG files, which can be used to conduct stored cross-site scripting attacks.
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 confidenceThe Smart Slider 3 WordPress plugin lacks proper capability validation on its upload function, allowing any authenticated user with contributor-level access or higher to upload arbitrary files including malicious SVG files that can execute JavaScript (stored XSS).

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 Smart Slider 3 plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and locate Smart Slider 3. Note the installed version number.Affected if Plugin is installed and active
-
Compare installed version to affected releasesCheck the plugin version against the version that includes the security fix (typically versions released after the CVE disclosure). If running an older version, the vulnerability may be present.Affected if Running a version predating the security patch
-
Confirm user role permissions allow contributor-level accessNavigate to Users > Roles in WordPress admin, or inspect the wp_roles table in the database. Verify which roles have access to the Smart Slider 3 upload functionality.Affected if Contributor, Author, or Editor roles can access file upload features in the plugin
-
Inspect uploaded SVG files for malicious contentCheck the wp-content/uploads/smart-slider-3/ directory (or similar upload paths) for SVG files. Examine file contents for script tags, onload attributes, or embedded JavaScript.Affected if SVG files containing executable JavaScript are present in uploads
You are affected if the Smart Slider 3 plugin is installed with a version predating the security patch AND non-administrator roles (contributor or higher) have access to the upload functionality.
Generated from the published advisory. Verify against your own configuration.
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 · scopedUpdate the plugin to the latest version which should include proper capability checks on the upload function, and restrict file upload permissions to administrator-level users only until patched.
Smart Slider 3 version 3.5.1.23 or later
- 1. Check current Smart Slider 3 plugin version installed on the WordPress site
- 2. Navigate to Plugins > Installed Plugins in WordPress admin dashboard
- 3. If the installed version is 3.5.1.22 or lower, update the plugin to the latest available version
- 4. Verify the update was successful and the new version is at least 3.5.1.23 or higher
- 5. Test file upload functionality to ensure the fix is working correctly
