CVE-2025-65239Public exploitNetwork attack vector

Authenticated log disclosure via trace endpoint

Published Nov 26, 2025 · Updated Nov 26, 2025

Incorrect access control in OpenCode Systems USSD Gateway 6.13.11 allows remote authenticated users to read server logs over the network. The /aux1/ocussd/trace endpoint returns trace-log contents to low-privilege accounts without enforcing the authorization required for those logs. Low-level access is sufficient, and the reported consequence is limited to log disclosure without data modification or service interruption.
