CVE-2026-32403
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 toocheke Toocheke Companion toocheke-companion allows DOM-Based XSS.This issue affects Toocheke Companion: from n/a through <= 1.194.
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 confidenceDOM-based Cross-site Scripting (XSS) vulnerability in Toocheke Companion allows attackers to inject malicious JavaScript through unsanitized user input that gets rendered directly into the browser DOM without proper encoding or validation.

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 Toocheke Companion installationSearch for Toocheke Companion files in your web application directory or check the application manifest/package files for the presence of this software componentAffected if The application is present and the installed version falls within any vulnerable version range (if known)
-
Identify user input entry pointsReview application source code for all locations where user-supplied data is accepted (URL parameters, form inputs, headers, cookies, localStorage) and subsequently used in client-side scriptsAffected if User input is accepted and passed to JavaScript without validation
-
Locate DOM manipulation codeSearch JavaScript files for patterns like innerHTML, outerHTML, insertAdjacentHTML, document.write, or similar DOM insertion methods that process user-supplied valuesAffected if The application uses these methods to render user input directly into the page DOM
-
Verify lack of output encodingInspect the DOM insertion code to confirm no context-aware encoding (HTML entity encoding, escaping of quotes) is applied to user input before DOM insertionAffected if User input is inserted into the DOM without sanitization, encoding, or validation functions
-
Trace data flow to DOMFollow the path from user input entry point through JavaScript code to the final DOM insertion point to confirm unsanitized input reaches the browser DOMAffected if Unsanitized user input flows directly from input source to DOM rendering
You are affected if Toocheke Companion is installed and the application renders user-supplied input into the browser DOM without proper encoding, validation, or sanitization, allowing script injection through the DOM.

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 context-aware output encoding and input validation on all user-supplied data before DOM insertion; use security libraries or Content Security Policy headers to prevent script execution.
