CVE-2026-5694
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 Quick Interest Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'loan-amount' and 'loan-period' parameters in all versions up to, and including, 3.1.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
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 Quick Interest Slider WordPress plugin fails to properly sanitize and escape the 'loan-amount' and 'loan-period' parameters, allowing unauthenticated attackers to inject malicious JavaScript that gets stored in the database and executed whenever users access affected pages.

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 plugin installationCheck if the Quick Interest Slider plugin exists in the WordPress plugins directory at wp-content/plugins/quick-interest-slider/ or list all installed plugins via WordPress admin under Plugins > Installed PluginsAffected if The plugin is present in the installation
-
Identify installed versionView the plugin header in the main plugin file (quick-interest-slider.php) to read the Version field, or check the plugin row in WordPress admin plugins listAffected if Version is lower than 3.1.6 or cannot be determined (indicating unpatched)
-
Verify vulnerable parameters are accessibleCheck if the plugin shortcode [quick_interest_slider] or its frontend forms handling 'loan-amount' and 'loan-period' parameters are present and active on any pageAffected if The plugin shortcode or form is deployed on any public-facing page
-
Scan database for injected scriptsQuery the WordPress options table (wp_options) and post meta table (wp_postmeta) for any records containing script tags, javascript:, or onload/onerror attributes in fields that may store loan-amount or loan-period valuesAffected if Suspicious script tags or event handlers are found stored in the database
The environment is affected if the Quick Interest Slider plugin is installed with a version below 3.1.6 and the plugin shortcode or form is active on any page, or if malicious scripts are found stored in the database.

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.
From vendor dataUpdate the plugin to the latest version (3.1.6 or later) which contains proper input sanitization and output escaping. If no patched version is available, remove the plugin until a fix is released.
