CVE-2025-26892
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 · uneditedUnrestricted Upload of File with Dangerous Type vulnerability in dkszone Celestial Aura allows Using Malicious Files.This issue affects Celestial Aura: from n/a through 2.2.
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 critical unrestricted file upload vulnerability in dkszone Celestial Aura (versions up to 2.2) allows attackers to upload malicious file types without validation, potentially enabling remote code execution by uploading executable files (e.g., PHP, JSP, ASP) that can then be accessed and executed on the server.

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 dkszone Celestial Aura installationSearch the system for Celestial Aura application files, check for installed packages, or look for the application in common web directories (e.g., /var/www/, /opt/, C:\inetpub\). Review any software inventory or application listings.Affected if The application is present on the system and handles file uploads.
-
Determine installed versionLocate version information - check application configuration files, about pages, or any version metadata files included with the installation. Compare the found version to the affected range (versions up to and including 2.2).Affected if The installed version is 2.2 or lower.
-
Verify file upload feature is enabledLocate the application's configuration files and look for upload-related settings. Check the web interface for file upload functionality. Inspect the application's routing or endpoint configuration for upload handlers.Affected if File upload functionality is present and accessible to users.
-
Inspect server-side file type validationExamine the application's source code, configuration, or web server settings for file upload validation logic. Look for file type allowlists or denylists, magic byte validation, or content-type checks in the upload handling code.Affected if No server-side file type validation exists, or validation relies solely on client-side checks or file extension matching without content verification.
-
Check upload directory configurationReview the web server and application configuration to determine where uploaded files are stored. Verify if the upload directory is within the webroot and whether script execution is disabled in that location.Affected if Uploaded files are stored within the webroot and can be directly accessed/executed via HTTP requests.
The environment is affected if dkszone Celestial Aura version 2.2 or lower is installed with its file upload feature enabled and without proper server-side file type validation, especially if the upload directory is web-accessible.

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 allowlist-based file type validation on both client and server sides, verify file content/magic bytes rather than just extensions, store uploads outside webroot, rename uploaded files, and disable script execution in upload directories.
