CVE-2026-41878: R-Soft Serwis Dms

High severity, CVSS 7.1. EPSS: 0.5% chance of exploitation in the next 30 days.

R-SOFT DMS is vulnerable to Insecure Direct Object Reference (IDOR) attack in multiple file download endpoints. The application fetches files from the database by ID and serves them to whoever requests them, relying only on session authentication, meaning any valid user can access any file. This issue was fixed in version v3.19-2862 and v3.17-2580.

Affected products

• R-Soft Serwis Dms: before v3.19-2862 (fixed in v3.19-2862); before v3.17-2580 (fixed in v3.17-2580)
