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 · unedited
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Tangible Loops & Logic tangible-loops-and-logic allows Stored XSS.This issue affects Loops & Logic: from n/a through <= 4.2.3.

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 confidence

Stored Cross-site Scripting (XSS) vulnerability in Tangible Loops & Logic plugin versions through 4.2.3 allows authenticated attackers to inject malicious JavaScript code through unsanitized user input that gets persisted on the server and executed in the browsers of other users viewing the affected content.

MitigationImplement proper input validation and output encoding/sanitization on all user-supplied input fields to neutralize XSS attack vectors; update to a patched version when released by the vendor.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Tangible Loops & Logic plugin is installed
    Locate the plugin in your WordPress installation under wp-content/plugins/ directory or check via WordPress admin plugin list
    Affected if plugin files exist in the plugins directory
  2. Identify installed plugin version
    Check the main plugin PHP file or readme.txt for the version number, or view version via WordPress admin plugin page
    Affected if version is 4.2.3 or lower
  3. Confirm user authentication is possible
    Verify that user accounts exist with permission to submit or edit content within the plugin (author role or higher)
    Affected if authenticated users can access plugin input fields
  4. Identify vulnerable input points
    Review plugin settings, template fields, or content creation areas where user-supplied text is accepted and stored
    Affected if unsanitized text input fields accept and persist user content that is later displayed to other users

You are affected if the Tangible Loops & Logic plugin is installed with version 4.2.3 or lower and authenticated users can submit content that gets stored and displayed to other users.
