CVE-2026-41031
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 · uneditedA Stored Cross-Site Scripting vulnerability in Vinna Process Monitor Version 4.0 Service Pack 1 (Build 63255) allows an authenticated remote attacker with low privileges to inject malicious JavaScript code into the application. This enables attackers to steal administrative access tokens and session credentials.
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 Stored Cross-Site Scripting vulnerability in Vinna Process Monitor v4.0 SP1 (Build 63255) allows low-privilege authenticated users to inject malicious JavaScript into application fields. This persisted script executes when viewed by higher-privileged users, enabling attackers to steal administrative session tokens and credentials.

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 installed Vinna Process Monitor versionLocate the application installation directory and check version information in the About dialog, help menu, or version file (often named version.txt, ver.info, or displayed on startup). Compare the build number to Build 63255 for v4.0 SP1.Affected if The installed version is Vinna Process Monitor v4.0 SP1 with Build 63255 exactly, or falls within this specific release.
-
Verify authenticated user access existsCheck if the application provides user authentication and allows low-privilege user accounts to log in. Review user role configurations or authentication logs to confirm low-privilege users can access the system.Affected if Low-privilege authenticated users can log into the application.
-
Identify input fields vulnerable to injectionLog in as a low-privilege user and navigate to common input fields such as process names, descriptions, comments, configuration labels, or any user-editable text fields. Attempt to input test script tags such as <script>alert(1)</script> into multiple text fields.Affected if Application accepts and stores user-supplied text in fields without immediate sanitization or rejection of HTML/script tags.
-
Confirm persistence of injected contentAfter submitting potentially malicious input, view the submitted data in the application interface to verify it was stored and persists across sessions or page reloads.Affected if Injected content persists in the database and is displayed back to users.
-
Test script execution when viewed by administratorsAs an administrator, view the page or record containing the low-privilege user's submitted content. Inspect the rendered HTML source to determine if script tags execute or are reflected without proper encoding.Affected if When viewed by administrators, the injected script executes or is rendered as raw HTML/JavaScript rather than being entity-encoded.
A user is affected if Vinna Process Monitor v4.0 SP1 (Build 63255) is installed, low-privilege authenticated users can input data into application fields, and stored scripts execute when administrators view that data.

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 for all user-supplied data before rendering and apply input validation with allowlist sanitization on the server side to prevent XSS injection points.
