CVE-2025-41060
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 vulnerability has been discovered in appRain CMF version 4.0.5, consisting of a stored authenticated XSS due to a lack of proper validation of user input, through the 'data[Addon][layouts]' and 'data[Addon][layouts_except]' parameters in /apprain/developer/addons/update/tree.
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 confidenceA stored authenticated Cross-Site Scripting (XSS) vulnerability exists in appRain CMF 4.0.5 due to insufficient input validation on the 'data[Addon][layouts]' and 'data[Addon][layouts_except]' parameters at the /apprain/developer/addons/update/tree endpoint. An authenticated attacker can inject malicious JavaScript code that persists in the application and executes when other users access the affected functionality.

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 appRain CMF versionLocate the version file or admin panel 'About' section to confirm the installed version is exactly 4.0.5Affected if installed version equals 4.0.5
-
Confirm Addon module is enabledCheck the application configuration files or admin settings to determine if the Addons module is activeAffected if Addon module is enabled and accessible
-
Identify accessible user accountsReview user accounts in the database or admin panel to determine which roles have access to the /apprain/developer/addons/update/tree endpointAffected if any authenticated user with Addon management permissions exists in the system
-
Inspect stored layout valuesQuery the database for any non-alphanumeric values in fields related to 'layouts' or 'layouts_except' in the addon configuration tableAffected if database contains layout values with script tags, event handlers, or other XSS payloads
-
Review application logsSearch access and error logs for requests to /apprain/developer/addons/update/tree containing suspicious patterns like <script, javascript:, or onload attributesAffected if logs show exploitation attempts against the vulnerable parameters
A user is affected if they run appRain CMF version 4.0.5 with the Addon module enabled and any authenticated user has access to the vulnerable endpoint, or if the layout parameters in the database already contain injected scripts.

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 strict input validation and output encoding for the affected parameters. Use a allowlist approach for valid input values and apply HTML entity encoding when rendering the layout values in the UI.
