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 · uneditedRukovoditel Project Management app 2.6 is affected by: Cross Site Scripting (XSS). An attacker can add JavaScript code to the filename.
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 confidenceRukovoditel Project Management app 2.6 contains a stored Cross-Site Scripting (XSS) vulnerability in the filename parameter. An attacker can inject malicious JavaScript code into a filename, which is then stored and executed when other users view or interact with the file, potentially allowing session hijacking or credential theft.

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 Rukovoditel versionAccess the application admin panel or check the installation directory for the version number. Look for 'About' or version information in the system settings or footer of the application pages.Affected if The installed version is exactly 2.6 (not higher or lower)
-
Confirm file upload module is accessibleLog in as a standard user and navigate to the project management or file management areas where files can be uploaded. Check if there is an option to upload attachments or files to records.Affected if The file upload functionality is available and accessible to users
-
Check for file rename or filename edit capabilityAfter uploading a file, look for options to edit the file name, add a description, or modify file metadata. This is typically found in file details, edit options, or properties panels.Affected if Users can modify or set custom filenames for uploaded files
-
Verify filename display without encodingUpload a test file with a simple name, then view it in the application. Access the same file from a different user account to confirm the filename is rendered in the interface (such as in file lists, attachments panel, or download links).Affected if Filenames are displayed directly in the web interface withoutevident sanitization or encoding
A user is affected if they are running Rukovoditel version 2.6 and have access to the file upload or file management features where custom filenames can be set and viewed by other users.

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 output encoding for all filename fields. Sanitize user-supplied filenames to remove or escape special characters, and ensure all user-controlled data is properly encoded before display to prevent XSS execution.
