CVE-2025-41061
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/uploadify.
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 confidenceStored authenticated XSS vulnerability in appRain CMF 4.0.5 allows authenticated attackers to inject malicious JavaScript through the 'data[Addon][layouts]' and 'data[Addon][layouts_except]' parameters in the /apprain/developer/addons/update/uploadify endpoint. The lack of input validation permits the payload to be stored and executed when other users view the affected pages.

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 installationIdentify if appRain CMF is installed by checking for characteristic files (e.g., /app/config/core.php, /app/webroot/index.php) or by accessing the application and identifying it uses the appRain framework.Affected if The system is running appRain CMF version 4.0.5 exactly.
-
Check installed versionLocate the version file or configuration that defines the appRain version. Common locations include /app/Config/version.php, /app/webroot/index.php, or the admin dashboard 'About' page.Affected if The installed version is 4.0.5 (exact match only).
-
Verify admin access existsDetermine if any user accounts exist with access to the /apprain/developer/addons/update/uploadify endpoint. This typically requires admin-level authentication.Affected if Authenticated admin accounts exist in the system, enabling access to the vulnerable endpoint.
-
Inspect addon layout configurationExamine the database or application configuration for any stored values in fields corresponding to 'data[Addon][layouts]' and 'data[Addon][layouts_except]'. These may be stored in the database table for addon configurations or in configuration files under /app/Config/.Affected if Malicious JavaScript payloads are present in addon layout-related configuration fields.
You are affected if appRain CMF version 4.0.5 is installed AND an authenticated user with access to the developer addons functionality exists in your environment.
Generated from the published advisory. Verify against your own configuration.
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 vulnerable parameters. Sanitize user-supplied addon layout data before storage and apply context-appropriate output encoding when rendering the data to prevent XSS execution.
