CVE-2025-41053
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/commonresource.
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 authenticated XSS vulnerability exists in appRain CMF 4.0.5 due to improper input validation of the 'data[Addon][layouts]' and 'data[Addon][layouts_except]' parameters in the /apprain/developer/addons/update/commonresource endpoint, allowing authenticated attackers to inject persistent malicious scripts.

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 appRain CMF installationLook for appRain CMF files in your webroot, typically in directories named 'apprain' or check your package manager for appRain installations.Affected if appRain CMF is not installed on the system
-
Identify installed versionCheck the version file or configuration within the appRain installation. Look for a version file typically located in the root appRain directory or check the admin panel for version information.Affected if The installed version is 4.0.5 specifically
-
Verify endpoint accessibilityAttempt to access the endpoint /apprain/developer/addons/update/commonresource through your web server. This endpoint is typically under the developer module.Affected if The endpoint returns a valid response (not 404 or 403) indicating the vulnerable code is present
-
Confirm authentication statusDetermine whether user accounts exist with access to the developer module and the addons update functionality. Check user role permissions in the appRain admin panel or user configuration.Affected if Authenticated users with developer or addon management privileges can access the vulnerable endpoint
-
Inspect stored parameter dataIf you have admin access, examine the addon configuration database records or files where 'layouts' and 'layouts_except' values are stored. Look for unsanitized HTML or script tags in these fields.Affected if The 'data[Addon][layouts]' or 'data[Addon][layouts_except]' parameters contain unescaped HTML or JavaScript characters that would execute in a user's browser
Your environment is affected if appRain CMF version 4.0.5 is installed and authenticated users can access the /apprain/developer/addons/update/commonresource endpoint with the vulnerable parameters.

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 context-aware output encoding for the affected parameters before rendering them in any application output.
