CVE-2026-27054
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 · uneditedImproper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in PenciDesign Penci Soledad Data Migrator penci-data-migrator allows Reflected XSS.This issue affects Penci Soledad Data Migrator: from n/a through <= 1.3.1.
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 reflected Cross-site Scripting (XSS) vulnerability exists in the Penci Soledad Data Migrator WordPress plugin (versions through 1.3.1). The plugin fails to properly sanitize user-supplied input before reflecting it back in web pages, allowing attackers to inject malicious JavaScript code that executes in the context of a victim's browser.

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 plugin is installedNavigate to WordPress admin dashboard > Plugins and look for 'Penci Soledad Data Migrator' in the installed plugins list. Check if it is activated.Affected if The plugin is installed and activated, making the vulnerable code active in the environment.
-
Identify installed versionIn the Plugins list, find the Penci Soledad Data Migrator entry. Click on the plugin name to view details, or inspect the plugin header in /wp-content/plugins/ directory to read the Version field from the main plugin file.Affected if The installed version is 1.3.1 or any earlier version, placing it within the affected range.
-
Locate vulnerable parameter input pointsReview the plugin settings pages and any publicly accessible forms or URLs that accept user input. Common XSS entry points in data migrator plugins include fields for importing data, configuring migration settings, or any parameter that gets reflected back in the page response.Affected if User-supplied input is reflected in the page output without sanitization, which is the core vulnerability condition.
-
Test for unsanitized reflectionUse browser developer tools or a web proxy to inspect HTTP responses when submitting input via the plugin's forms or URL parameters. Check if special characters like <script> or javascript: are returned unescaped in the HTML response.Affected if The response contains raw user input in the HTML without proper encoding (e.g., <script> appears as <script>), confirming the XSS vulnerability is present and exploitable.
A user is affected if the Penci Soledad Data Migrator plugin is installed at version 1.3.1 or earlier and the plugin reflects user input back into web pages without sanitization.

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 dataImplement proper input validation and output encoding/sanitization for all user-supplied data that gets reflected in web pages. Consider using WordPress built-in sanitization functions like esc_html(), esc_attr(), or wp_kses() to neutralize malicious input.
