CVE-2025-56466 is a security vulnerability identified in the Android application Dietly version 1.25.0. The vulnerability arises from the presence of hardcoded credentials within the application. Hardcoded credentials refer to fixed usernames, passwords, API keys, or tokens embedded directly in the application's source code or binaries. Such credentials can be extracted by attackers through reverse engineering or static analysis of the app, enabling unauthorized access to sensitive information or backend services. In this case, the hardcoded credentials allow attackers to gain access to sensitive information, though the exact nature of the data exposed is not detailed. The vulnerability does not have a CVSS score assigned yet, and no known exploits are reported in the wild as of the publication date. The affected version is specified as 1.25.0 for Android, but no further version details are provided. The lack of patch information suggests that a fix may not yet be available or publicly disclosed. This vulnerability is significant because mobile applications often handle personal or sensitive user data, and embedded credentials can provide attackers with a direct path to compromise user privacy or backend systems. The exploitation likely requires an attacker to obtain the application package (APK) and perform analysis to extract the credentials, which is feasible for motivated adversaries. The vulnerability impacts confidentiality primarily, with potential secondary impacts on integrity and availability depending on what the credentials grant access to.

For European organizations, the impact of this vulnerability depends on the usage of the Dietly app within their user base or internal operations. If Dietly is used by employees or customers, attackers exploiting this vulnerability could access sensitive user data or backend services linked to the app. This could lead to data breaches involving personal information, financial data, or proprietary business information. The exposure of hardcoded credentials may also facilitate lateral movement within corporate networks if the credentials provide access to internal APIs or services. Additionally, regulatory implications under GDPR are significant; unauthorized access to personal data could result in legal penalties and reputational damage. Since the vulnerability affects an Android app, organizations with a mobile workforce or customers relying on Android devices are at higher risk. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability is public. The potential for sensitive information disclosure makes this a concern for sectors handling confidential data, such as finance, healthcare, and government entities in Europe.

To mitigate this vulnerability, European organizations and users should: 1) Immediately check if Dietly v1.25.0 is deployed or used within their environment and restrict its use until a patch is available. 2) Monitor for updates from the vendor and apply patches promptly once released. 3) Conduct static and dynamic analysis of the app binaries to detect hardcoded credentials proactively in other applications. 4) Employ mobile application management (MAM) solutions to control app usage and enforce security policies on Android devices. 5) Educate users about the risks of installing untrusted or outdated applications. 6) If possible, replace Dietly with alternative applications that follow secure credential management practices. 7) Implement network segmentation and least privilege access controls to limit the impact if credentials are compromised. 8) Monitor network and application logs for suspicious activity that could indicate exploitation attempts. These steps go beyond generic advice by focusing on immediate containment, proactive detection, and organizational controls tailored to mobile app vulnerabilities.
