CVE-2025-23661
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 · uneditedCross-Site Request Forgery (CSRF) vulnerability in ryscript NV Slider nv-slider allows Stored XSS.This issue affects NV Slider: from n/a through <= 1.6.
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 confidenceA CSRF vulnerability in ryscript NV Slider (versions <=1.6) allows attackers to craft malicious requests that store XSS payloads within the slider component. When other users view or interact with the compromised slider, the stored JavaScript executes in their browsers, enabling session hijacking, credential theft, or further website compromise.

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.
-
Identify if NV Slider is installedLocate the ryscript NV Slider component in your CMS/plugins directory, or check your website's frontend for any slider functionality that matches the NV Slider plugin behaviorAffected if The plugin/component is present in your environment
-
Verify the installed versionCheck the version metadata of the NV Slider plugin (typically found in a version.php, plugin.json, or readme file within the plugin directory)Affected if The installed version is 1.6 or any version lower than 1.6
-
Inspect slider configuration for XSS payloadsAccess the database tables or configuration files where slider content is stored (often named like nv_slider_slides, slider_items, or similar), and examine any text fields for suspicious patterns such as <script tags, javascript: URIs, event handlers like onload/onerror, or encoded variationsAffected if Any slider records contain XSS payloads (script tags, javascript: protocols, or event handler attributes)
-
Check for CSRF protection on slider admin actionsExamine the HTTP requests made when saving/updating slider content through the admin interface; verify if anti-CSRF tokens are included in the request headers or form data for state-changing operationsAffected if State-changing slider operations (add/edit/delete slides) lack CSRF token validation
You are affected if NV Slider version 1.6 or lower is installed AND the slider admin interface lacks CSRF protection, or if XSS payloads are already present in slider data.
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 · scopedImplement anti-CSRF tokens for all state-changing operations and validate the Origin/Referer headers. Additionally, apply proper output encoding and input validation to prevent XSS injection via the CSRF vector.
Latest version of NV Slider (rys NV Slider) from vendor repository (version > 1.6)
- Identify the current version of NV Slider (rys NV Slider) being used in the application
- Check the official ryscript plugin repository or WordPress plugin directory for the latest available version of NV Slider
- Upgrade NV Slider to the latest version available from the vendor (version higher than 1.6)
- After upgrading, verify that the CSRF protection mechanisms are properly implemented by testing form submissions and slider configuration changes
- Ensure that the WordPress nonce verification is in place for all admin actions related to slider management
