CVE-2025-48582 is an elevation of privilege vulnerability identified in Google Android versions 14, 15, and 16. The issue arises from multiple locations within the Android system where an intent redirect flaw allows deletion of media files without requiring the MANAGE_EXTERNAL_STORAGE permission. Normally, this permission is necessary to manage or delete external storage files, but due to improper intent handling, an attacker can bypass this restriction. The vulnerability is classified under CWE-59, which involves improper link resolution or redirection, leading to unauthorized actions. Exploitation requires only local access with no additional execution privileges or user interaction, making it a potent local escalation vector. The CVSS v3.1 score of 8.4 reflects high severity, with impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). The attacker can delete media files, potentially causing data loss or disruption of services relying on media content. No patches are currently linked, and no known exploits have been reported in the wild. However, the ease of exploitation and the broad impact necessitate urgent attention from organizations and device users. The flaw could be leveraged by malicious apps or local attackers to escalate privileges and compromise device integrity.

The vulnerability allows local attackers to bypass critical permission checks and delete media files, impacting the confidentiality, integrity, and availability of user data. For organizations, this could lead to loss of sensitive media, disruption of business processes relying on Android devices, and potential further exploitation if combined with other vulnerabilities. The ability to escalate privileges without user interaction or additional execution rights increases the risk of automated or stealthy attacks. This could affect enterprise environments where Android devices are used for sensitive communications or data storage. Additionally, the deletion of media files could disrupt forensic investigations or data recovery efforts. The broad impact on multiple Android versions means a large number of devices worldwide are potentially vulnerable, increasing the attack surface significantly.

Organizations and users should monitor official Google security advisories and apply patches promptly once they become available. Until patches are released, restrict installation of untrusted or unnecessary applications that might exploit local vulnerabilities. Implement application whitelisting and use mobile device management (MDM) solutions to enforce security policies and limit local access. Developers should validate and sanitize intents rigorously to prevent redirect-based privilege escalations. Security teams should audit Android devices for unusual media deletion activities and monitor logs for suspicious intent usage. Employ endpoint detection and response (EDR) tools capable of detecting local privilege escalation attempts. Educate users about the risks of installing apps from unknown sources and encourage the use of Google Play Protect or similar security services. Finally, consider isolating critical Android devices or limiting their exposure to untrusted networks to reduce the risk of local exploitation.
