What is CVE-2026-41877?

R-SOFT DMS is susceptible to a Stored Cross-Site Scripting vulnerability in its file upload feature. This flaw allows an authenticated attacker to inject malicious HTML and JavaScript code into the filename during the upload process. The injected content is executed when other users access the file list or upload status, potentially compromising their security. The issue is mitigated in versions later than v3.19-2832 and v3.17-2580.
