CVE-2025-56466 is a high-severity vulnerability identified in the Android application Dietly version 1.25.0. The core issue stems from the presence of hardcoded credentials within the app, classified under CWE-798 (Use of Hard-coded Credentials). These credentials are embedded directly in the application's code or resources, allowing attackers to extract them without requiring authentication or user interaction. Exploiting this vulnerability enables an attacker to gain unauthorized access to sensitive information managed or accessible through the Dietly app. The CVSS 3.1 base score of 7.5 reflects a network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N), with a high impact on confidentiality (C:H) but no impact on integrity or availability (I:N/A:N). Although no known exploits are currently reported in the wild, the vulnerability's nature makes it a significant risk, especially if attackers reverse-engineer the app to extract these credentials. The absence of patch links suggests that a fix has not yet been publicly released or documented. Given the app's Android platform, the vulnerability affects mobile devices running this specific version of Dietly, potentially exposing user data or backend services accessed via these credentials.

For European organizations, especially those involved in health, nutrition, or wellness sectors that may use or integrate Dietly for dietary management or related services, this vulnerability poses a substantial risk. Attackers leveraging hardcoded credentials can bypass authentication controls, leading to unauthorized data disclosure. This could result in exposure of personal health information, user profiles, or other sensitive data, potentially violating GDPR and other privacy regulations. The confidentiality breach could damage organizational reputation, invite regulatory fines, and erode user trust. Additionally, if these credentials provide access to backend APIs or cloud services, attackers might pivot to more extensive network intrusions or data exfiltration. The lack of required privileges or user interaction lowers the barrier for exploitation, increasing the likelihood of automated or mass attacks targeting vulnerable devices across Europe. Mobile workforce and BYOD policies in European enterprises could further expand the attack surface, as compromised devices may connect to corporate networks.

To mitigate this vulnerability effectively, European organizations and users should: 1) Immediately audit the use of Dietly v1.25.0 within their environments and identify all affected devices. 2) Monitor for updates or patches from the vendor addressing this vulnerability and prioritize prompt application once available. 3) If no patch is available, consider temporarily discontinuing the use of the affected app version or restricting its network access using mobile device management (MDM) solutions to limit communication with backend services. 4) Employ runtime application self-protection (RASP) or mobile threat defense (MTD) tools to detect anomalous app behavior indicative of exploitation attempts. 5) Educate users about the risks of using outdated or unpatched applications and encourage regular updates. 6) For developers or integrators, avoid embedding credentials in application code; instead, use secure credential storage mechanisms and dynamic authentication flows. 7) Implement network-level controls such as API gateways with strong authentication and anomaly detection to prevent misuse of compromised credentials. 8) Conduct regular security assessments and penetration testing focusing on mobile applications and their backend integrations to detect similar vulnerabilities proactively.
