CVE-2026-78212Network attack vector

Unauthenticated file read via relative path traversal

Published Aug 24, 2026 · Updated Aug 24, 2026

Relative path traversal in 4MOSAn Management Center before 20260621 allows remote attackers to download arbitrary system files. Public records identify improper handling of traversal sequences but do not disclose the vulnerable endpoint, parameter, or pathname-handling function. No authentication or user interaction is required, and the reported consequence is confined to file disclosure without integrity or availability impact.
