CVE-2025-53505Network attack vector

Server information disclosure via path traversal

Published Aug 21, 2025 · Updated Aug 21, 2025

Path traversal in Intermesh BV GroupOffice before 6.8.119 and before 25.0.20 allows remote authenticated users to read server data. Intermesh BV has not published the affected component or the pathname operation that fails to confine attacker-controlled paths. Low-privileged network access is sufficient, and the reported consequence is limited to reading information from the hosting server.
