CVE-2025-15464 is a vulnerability identified in the yintibao Fun Print Mobile Android application, specifically version 6.05.15. The root cause is an improperly exported Activity component, classified under CWE-926, which allows external applications to gain access to the application context. This flaw enables an attacker to directly launch the Gmail application with inbox access, effectively bypassing Android's security controls that normally restrict inter-application data access. The vulnerability is remotely exploitable without requiring any privileges or user interaction, making it particularly dangerous. The CVSS v3.1 base score of 7.5 indicates a high severity level, primarily due to the high impact on confidentiality (C:H), with no impact on integrity or availability. This means attackers can read sensitive email content but cannot modify or disrupt services. Although no exploits have been reported in the wild yet, the vulnerability presents a significant risk of data leakage and privacy breaches. The lack of patches or mitigation links suggests that users and administrators should be vigilant and apply any forthcoming updates promptly. The vulnerability arises from improper Android component export configurations, which should be carefully managed to prevent unauthorized access. The affected product is a mobile printing application, which may be used in various business environments, increasing the potential attack surface.

For European organizations, the primary impact of CVE-2025-15464 is the potential unauthorized disclosure of sensitive email information through the Gmail app on compromised Android devices running the vulnerable Fun Print Mobile app. This can lead to breaches of confidentiality, exposing corporate communications, personal data, and potentially sensitive attachments. Since the vulnerability does not affect integrity or availability, the main concern is data leakage. Organizations relying on Android devices with this app installed, especially in sectors handling confidential information such as finance, healthcare, and government, face increased risk of espionage or data theft. The ease of exploitation without user interaction or privileges means attackers can automate attacks, increasing the threat level. Additionally, regulatory compliance risks arise under GDPR due to potential unauthorized access to personal data. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits rapidly once the vulnerability is public. The vulnerability could also be leveraged as part of multi-stage attacks targeting mobile endpoints.

To mitigate CVE-2025-15464, developers of the Fun Print Mobile app must revise the AndroidManifest.xml to ensure that Activities and other components are not exported unless explicitly required. Specifically, the vulnerable Activity should have the attribute android:exported="false" or be protected with appropriate permissions to restrict access. Implementing intent filters carefully to avoid unintended exposure is critical. Organizations should monitor for updates or patches from yintibao and apply them immediately once available. Until a patch is released, users should consider uninstalling the app or restricting its use on devices that access sensitive information. Mobile device management (MDM) solutions can be used to control app installations and enforce security policies. Additionally, organizations should educate users about the risks of installing untrusted apps and monitor network traffic for unusual activity related to Gmail or the Fun Print Mobile app. Employing endpoint detection and response (EDR) tools on mobile devices can help detect exploitation attempts. Finally, auditing app permissions and reviewing exported components in all enterprise mobile apps can prevent similar vulnerabilities.
