Technical Analysis
CVE-2026-110618 describes a missing authentication vulnerability in the AndServer HTTP server used by SmsForwarder through version 3.5.0. Due to the lack of authentication on critical remote-control API endpoints enabled by default, unauthenticated attackers on the network can perform sensitive actions such as reading SMS messages, call logs, contacts, sending SMS messages, and exporting or overwriting the application's configuration via the clone API. This vulnerability exposes sensitive user data and control functions without requiring any privileges or user interaction.
Potential Impact
An attacker can remotely access and manipulate sensitive user data including SMS messages, call logs, and contacts without authentication. They can also send SMS messages and modify or export the application's configuration, potentially leading to privacy breaches and unauthorized actions on the affected device. The vulnerability is rated high severity with a CVSS 4.0 score of 8.6, indicating significant impact on confidentiality and integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to the SmsForwarder HTTP server and disable or secure the remote-control APIs if possible to prevent unauthorized access.
