CVE-2025-61220 is a vulnerability identified in the AutoBizLine Android application (package com.mysecondline.app) version 1.2.91. The root cause is an incomplete verification mechanism that fails to properly authenticate users during the login process. This flaw allows an attacker to bypass authentication controls and impersonate other users, thereby gaining unauthorized access to sensitive personal information stored or accessible via the app. The vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor), indicating that confidentiality is compromised. The CVSS v3.1 score is 7.5 (high), with vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, meaning it is remotely exploitable over the network without any privileges or user interaction, and it impacts confidentiality only, not integrity or availability. No patches or fixes have been published yet, and no known exploits have been reported in the wild. The vulnerability poses a significant risk to users’ privacy and could lead to data breaches if exploited. The lack of authentication enforcement suggests a fundamental flaw in the app’s session or token validation logic, possibly due to missing or incorrect server-side checks or insecure client-side logic. Organizations relying on this app for business communications or transactions may face compliance and reputational risks if user data is exposed.

For European organizations, the impact of CVE-2025-61220 is primarily a breach of confidentiality, potentially exposing sensitive personal or business information of users. This could lead to privacy violations under GDPR, resulting in regulatory fines and legal consequences. Unauthorized access to user accounts may also facilitate further attacks such as social engineering or identity theft. The vulnerability could undermine trust in the affected application, disrupting business operations that depend on secure communications. Since the app is mobile-based, employees using it for business purposes may inadvertently expose corporate data. The lack of integrity and availability impact reduces the risk of system disruption, but the confidentiality breach alone is significant. Organizations may also face indirect impacts such as damage to brand reputation and customer trust. The absence of a patch increases the window of exposure, making proactive mitigation critical.

1. Immediately audit and inventory all instances of AutoBizLine app usage within the organization to identify affected users. 2. Until a patch is released, restrict or disable the use of version 1.2.91 of the app on corporate devices. 3. Implement network-level controls such as firewall rules or VPN restrictions to limit app access to trusted networks. 4. Monitor network traffic and authentication logs for suspicious login attempts or anomalous access patterns indicative of exploitation attempts. 5. Educate users about the vulnerability and advise against using the app for sensitive communications until fixed. 6. Coordinate with the app vendor to obtain timely patches and verify the effectiveness of fixes once available. 7. Consider deploying additional multi-factor authentication (MFA) mechanisms at the organizational level to reduce the risk of unauthorized access. 8. Review and enhance endpoint security controls on mobile devices to detect and prevent exploitation attempts. 9. Prepare incident response plans specific to potential data breaches stemming from this vulnerability. 10. Regularly update and patch all mobile applications and underlying operating systems to minimize exposure to similar vulnerabilities.
