CVE-2025-41057
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/rich_text_editor.
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 confidenceStored authenticated XSS vulnerability in appRain CMF 4.0.5 allows authenticated users to inject malicious JavaScript through the 'data[Addon][layouts]' and 'data[Addon][layouts_except]' parameters in the rich_text_editor addon update page at /apprain/developer/addons/update/rich_text_editor. The lack of input validation allows the XSS payload to persist and execute when other users view the affected content.

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 check the admin dashboard for the installed appRain version. Common locations include a version.php file in the app/Config directory or the About section in the admin panel.Affected if The installed version is appRain 4.0.5
-
Confirm rich_text_editor addon is installedNavigate to the addons management section in the appRain admin panel or inspect the app/Addons directory to verify the rich_text_editor addon is present and enabled.Affected if The rich_text_editor addon is installed and active on the system
-
Inspect the vulnerable update pageAccess the URL path /apprain/developer/addons/update/rich_text_editor while authenticated as a user with developer or admin privileges to view the addon configuration form.Affected if You can access the rich_text_editor addon update page and view the 'layouts' and 'layouts_except' input fields
-
Check stored parameter values in database or configExamine the database table storing addon configurations (commonly in the addon_settings or similar table) or inspect the configuration files for the 'data[Addon][layouts]' and 'data[Addon][layouts_except]' parameters.Affected if These parameters contain raw, unsanitized input that could include script tags or event handlers
You are affected if running appRain CMF version 4.0.5 with the rich_text_editor addon enabled and the vulnerable parameters contain unsanitized user-supplied content that could execute JavaScript.

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 'data[Addon][layouts]' and 'data[Addon][layouts_except]' parameters. Sanitize all user-supplied input before storage and apply contextual output encoding when rendering the data.
