CVE-2026-20995 is a vulnerability classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) found in Samsung Mobile's Smart Switch application versions prior to 3.7.69.15. The flaw allows remote attackers to access sensitive functionality without authentication, enabling them to set specific configurations on the device remotely. The vulnerability is exploitable over the network (AV:N) with low attack complexity (AC:L), requiring no privileges (PR:N) or user interaction (UI:P). The impact includes limited confidentiality and integrity loss (VC:N, VI:L, VA:L), with no impact on system availability or scope changes. The vulnerability arises from improper access control, exposing configuration interfaces that should be restricted. Although no public exploits are known, the vulnerability poses a risk of unauthorized configuration changes that could lead to further compromise or data leakage. The lack of patches at the time of reporting necessitates cautious network exposure and monitoring. The vulnerability affects Samsung Mobile Smart Switch users globally, especially those using older versions prior to 3.7.69.15. The CVSS 4.0 score of 5.3 indicates a medium severity level, balancing ease of exploitation against limited impact and scope.

The vulnerability allows remote attackers to set specific configurations on Samsung devices via the Smart Switch application without authentication, potentially leading to unauthorized changes in device behavior or exposure of sensitive information. This can undermine the confidentiality and integrity of user data and device settings. While the availability impact is minimal, unauthorized configuration changes could facilitate further attacks or data leakage. Organizations relying on Smart Switch for device management or data transfer may face risks of unauthorized access or manipulation of device configurations, potentially affecting enterprise mobile security. The absence of known exploits reduces immediate risk, but the ease of exploitation and network accessibility mean that attackers could leverage this vulnerability in targeted campaigns. The impact is particularly relevant for environments with high Samsung device usage, including enterprises and consumers, where unauthorized configuration changes could disrupt operations or compromise sensitive data.

1. Update Samsung Smart Switch to version 3.7.69.15 or later as soon as patches become available to remediate the vulnerability. 2. Until patches are applied, restrict network access to Smart Switch services by implementing firewall rules or network segmentation to limit exposure to trusted networks only. 3. Monitor network traffic for unusual configuration requests or unauthorized access attempts targeting Smart Switch interfaces. 4. Employ endpoint security solutions that can detect anomalous behavior related to configuration changes on Samsung devices. 5. Educate users and administrators about the risks of using outdated Smart Switch versions and encourage timely updates. 6. Review and harden device configuration policies to minimize the impact of unauthorized changes. 7. Coordinate with Samsung support channels for any interim mitigation advice or updates on patch availability.
