Description OSIDB Bzimport 2026-11-11 18:21:42 UTC 
OpsTree REMS through 1.0.0 contains a server-side request forgery vulnerability that allows authenticated users to make the backend connect to arbitrary destinations through the database Test Connection feature. Attackers can set a database entry's host and port to localhost, internal addresses, or attacker-controlled servers to probe internal hosts and ports reachable from the REMS server.
