CVE-2025-53649 is a vulnerability identified in the SwitchBot App for iOS and Android, specifically affecting versions V6.24 through V9.12. The vulnerability involves the insertion of sensitive user information into application log files. When the app processes certain operations, it inadvertently records sensitive data within logs that are stored on the device. These logs, if accessed by an attacker with local access to the device or through other means, could expose confidential user information. The vulnerability does not require user interaction or authentication to be exploited, but it does require local access to the application logs, which typically reside on the device's storage. The CVSS 3.0 score assigned is 5.1 (medium severity), with the vector indicating local attack vector (AV:L), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and no availability impact (A:N). This means that while the vulnerability does not allow remote exploitation or modification of data, it can lead to significant confidentiality breaches if an attacker gains access to the logs. The vulnerability is present in both major mobile platforms (iOS and Android), affecting a broad user base. No known exploits are currently in the wild, and no patches or mitigation links have been published at the time of this report. The vulnerability stems from improper handling of sensitive data within the app's logging mechanisms, a common issue in mobile applications that can lead to leakage of credentials, tokens, or other private information if logs are not properly sanitized or protected.

For European organizations, the impact of this vulnerability depends largely on the use of SwitchBot devices and the associated mobile app within their environments. SwitchBot products are popular in smart home and office automation, often used to control physical devices remotely. Exposure of sensitive information through logs could lead to unauthorized access to these devices, potentially compromising physical security or privacy. In corporate environments where employees use SwitchBot apps on corporate devices, sensitive information leakage could extend to user credentials or tokens that might be reused or leveraged in broader attacks. Although the vulnerability requires local access to the device or logs, the risk increases in scenarios where devices are shared, lost, or compromised by malware that can access application data. The confidentiality breach could also expose personal user data, leading to privacy violations under GDPR regulations, which are stringent in Europe. The medium severity rating suggests that while the vulnerability is not critical, it poses a tangible risk that could be exploited in targeted attacks or combined with other vulnerabilities for greater impact.

Organizations and users should immediately verify the version of the SwitchBot app installed on their devices and update to a version beyond V9.12 once a patch is released by the vendor. Until an official patch is available, users should minimize the risk by restricting physical and local access to devices running the vulnerable app. This includes enforcing strong device-level authentication, encrypting device storage, and avoiding the use of shared or public devices for controlling SwitchBot products. Additionally, organizations should monitor for any unusual access patterns or attempts to access application logs on managed devices. Mobile Device Management (MDM) solutions can be configured to restrict access to app data directories and enforce security policies. Developers and security teams should advocate for the vendor to implement secure logging practices, such as redacting sensitive information from logs and using secure storage mechanisms. Regular audits of application logs and security reviews of mobile apps used within the organization are recommended to detect similar issues proactively.
