CVE-2026-41877 is a stored cross-site scripting vulnerability in R-SOFT DMS affecting versions before v3.19-2832 and before v3.17-2580. The flaw is present in the file upload functionality, where user-controlled file names are not properly sanitized or encoded before being rendered in the application interface. An authenticated attacker can upload a file whose name contains arbitrary HTML or JavaScript, causing the payload to be persistently stored and later executed in the browsers of other users when they view the file list or upload status pages.
