CVE-2025-58486 is a vulnerability identified in Samsung Account software versions prior to 15.5.01.1, classified under CWE-20 for improper input validation. This flaw allows a local attacker to execute arbitrary scripts within the context of the Samsung Account application. The vulnerability arises because the application fails to properly validate input data, enabling script injection attacks. Exploitation requires local access to the device, meaning the attacker must have physical or logical access to the user environment without needing elevated privileges or user interaction. The CVSS 3.1 base score is 4.0, indicating a medium severity level, with the vector AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N. This means the attack vector is local, attack complexity is low, no privileges or user interaction are required, and the impact is limited to confidentiality loss without affecting integrity or availability. No known exploits are currently reported in the wild, and no patches or updates are explicitly linked in the provided data, though the fixed version is 15.5.01.1 or later. The vulnerability could be leveraged to execute arbitrary scripts, potentially leading to information disclosure or further local exploitation chains. Given Samsung Account's integration with mobile devices, this vulnerability primarily affects Samsung mobile users who have the vulnerable software installed.

For European organizations, the primary impact of CVE-2025-58486 lies in the potential confidentiality breach of sensitive account information stored or accessible via Samsung Account. Since exploitation requires local access, the risk is higher in environments where devices are shared, lost, or physically accessible by unauthorized personnel. This could lead to leakage of personal or corporate data tied to Samsung Account credentials or session information. The vulnerability does not affect data integrity or system availability, limiting the scope of damage. However, in sectors with strict data protection regulations like GDPR, even confidentiality breaches can have significant compliance and reputational consequences. Organizations with mobile workforces using Samsung devices are particularly at risk. The lack of known exploits reduces immediate threat but does not eliminate future risk, especially if attackers develop local attack vectors or combine this vulnerability with others. The medium severity score suggests moderate urgency in remediation to prevent potential targeted attacks or insider threats.

To mitigate CVE-2025-58486, organizations should ensure all Samsung devices are updated to Samsung Account version 15.5.01.1 or later, where the input validation flaw is fixed. Since no direct patch links are provided, users should rely on official Samsung software updates and verify version compliance. Additionally, organizations should enforce strict local device access controls, including strong device authentication, screen locks, and user session management to prevent unauthorized local access. Employ mobile device management (MDM) solutions to monitor and restrict installation of vulnerable software versions. Educate users about the risks of leaving devices unattended and the importance of applying updates promptly. For sensitive environments, consider disabling or limiting Samsung Account usage if feasible. Regularly audit devices for compliance and monitor for unusual local activity that could indicate exploitation attempts. Finally, maintain an incident response plan that includes local device compromise scenarios.
