Summary
An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev11. The API to configure external mail accounts can be abused to map and access network components within the trust boundary of the operator. Users can inject arbitrary hosts and ports to API calls. Depending on the response type, content and latency, information about existence of hosts and services can be gathered. Attackers can get internal configuration information about the infrastructure of an operator to prepare subsequent attacks.
Exploit prediction
1.19% chance of exploitation in the next 30 days, higher than 68% of all scored CVEs (FIRST EPSS, 2026-11-08).
