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 · uneditedDeserialization of Untrusted Data vulnerability in Averta Master Slider.This issue affects Master Slider: from n/a through 3.9.5.
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 deserialization vulnerability in Averta Master Slider allows attackers to deserialize untrusted data, likely through unsafe use of PHP unserialize() on user-controlled input. This can lead to code execution depending on available gadget chains in the application environment.

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.
-
Confirm Master Slider plugin installationLocate the Master Slider plugin files in the WordPress plugins directory (wp-content/plugins/master-slider) or check the plugin admin panel for presence of Averta Master SliderAffected if Master Slider plugin is not found in the installation
-
Identify installed versionOpen the main plugin file (typically master-slider.php) and locate the version definition, or check the plugin admin panel version displayAffected if The version number is less than 3.9.7 or cannot be determined (missing version file)
-
Search for unsafe deserialization callsGrep the plugin directory for PHP files containing 'unserialize(' without prior sanitization or validation. Look for patterns like unserialize($_POST, unserialize($_GET, or unserialize($_REQUESTAffected if Files contain unserialize() calls operating on user-controlled input without sanitization
-
Inspect AJAX handlers for deserialization inputExamine AJAX action handlers in the plugin (typically in ajax/ folder or within main PHP files) and check if unserialize() is called on data from $_POST, $_GET, or $_REQUEST parametersAffected if AJAX endpoints accept serialized data from user input without validation
-
Check for publicly accessible deserialization entry pointsReview the plugin's exposed endpoints and routes. Identify which PHP files process incoming requests and determine if unserialize() is reachable without authenticationAffected if Unserialize operations are reachable via publicly accessible endpoints without authentication checks
The environment is affected if Master Slider is installed with a version lower than 3.9.7 and the plugin contains reachable unsafe deserialization code that processes user-controlled input.

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 · scoped3.9.7
Upgrade to the latest version of Master Slider if a patch is available; otherwise, restrict plugin access, implement WAF rules for serialized data, and audit the plugin's AJAX handlers and endpoints for unsafe deserialization calls.
Master Slider version 3.9.7 or later
- Log in to the WordPress admin dashboard
- Navigate to Plugins > Installed Plugins
- Find 'Master Slider' in the plugin list
- Check if the current version is below 3.9.7
- If vulnerable, click 'Update Now' to install the latest version (3.9.7 or later)
- Verify the update was successful and the plugin is functioning correctly
