CVE-2025-48567 is a vulnerability affecting Google Android versions 14 through 16, involving an elevation of privilege through a bypass of file path filtering mechanisms. The root cause is incorrect Unicode normalization, which allows attackers to craft file paths that evade security filters designed to restrict access to sensitive directories. This flaw enables a local attacker, who already has limited access, to escalate privileges without requiring additional execution rights. The vulnerability requires user interaction, such as opening a malicious file or link, to trigger the exploit. The issue is categorized under CWE-22, indicating a path traversal weakness. The CVSS v3.1 score of 7.8 reflects high severity, with impacts on confidentiality, integrity, and availability. Although no public exploits have been reported, the vulnerability poses a significant risk due to the widespread use of affected Android versions and the critical nature of the privilege escalation. The lack of available patches at the time of publication increases the urgency for mitigation.

If exploited, this vulnerability allows attackers to bypass file path restrictions and gain elevated privileges on affected Android devices. This can lead to unauthorized access to sensitive data, modification or deletion of critical system files, and potential disruption of device functionality. The compromise of confidentiality, integrity, and availability could facilitate further attacks, including installation of persistent malware or spying on users. Given the ubiquity of Android devices globally, the impact extends to millions of users and organizations relying on these devices for communication and business operations. The requirement for user interaction limits remote exploitation but does not eliminate risk, especially in targeted phishing or social engineering campaigns. The absence of known exploits currently provides a window for remediation before widespread abuse occurs.

Organizations and users should prioritize updating to patched Android versions once available from Google or device manufacturers. Until patches are released, users should exercise caution with unsolicited files, links, or apps, especially from untrusted sources. Employing mobile device management (MDM) solutions can help enforce security policies and restrict installation of unverified applications. Developers and security teams should audit file path handling and Unicode normalization processes in their applications to prevent similar bypasses. Additionally, enabling strong endpoint protection and monitoring for unusual local privilege escalation attempts can aid in early detection. Security awareness training focused on phishing and social engineering can reduce the likelihood of user interaction-based exploitation. Vendors should expedite patch development and communicate clear guidance to users and administrators.
