CVE-2026-35394: CWE-939: Improper Authorization in Handler for Custom URL Scheme in mobile-next mobile-mcp
CVE-2026-35394 is a high-severity vulnerability in mobile-next's mobile-mcp server prior to version 0. 0. 50. The mobile_open_url tool improperly handles user-supplied URLs by passing them directly to Android's intent system without validating the URL scheme. This allows an attacker to execute arbitrary Android intents, including potentially dangerous actions such as USSD codes, phone calls, SMS messages, and accessing content providers. The vulnerability is fixed in version 0. 0. 50.
AI Analysis
Technical Summary
The vulnerability arises from improper authorization in the handler for custom URL schemes within the mobile_open_url tool of mobile-mcp. Before version 0.0.50, the tool forwards user-supplied URLs directly to Android's intent system without validating the scheme, enabling execution of arbitrary intents. This can lead to unauthorized actions on the affected Android device, including initiating phone calls, sending SMS messages, executing USSD codes, and accessing content providers. The issue is classified under CWE-939 (Improper Authorization). The vulnerability has a CVSS 3.1 base score of 8.3, indicating high severity. It is fixed in version 0.0.50 of mobile-mcp.
Potential Impact
Exploitation of this vulnerability allows an attacker to execute arbitrary Android intents on the affected device. This can result in unauthorized information disclosure (low confidentiality impact), high integrity impact due to unauthorized actions like sending SMS or making phone calls, and high availability impact by potentially disrupting device functionality. The vulnerability requires no privileges but does require user interaction (UI required).
Mitigation Recommendations
This vulnerability is fixed in mobile-mcp version 0.0.50. Users and administrators should upgrade to version 0.0.50 or later to remediate this issue. Since no official patch link or advisory is provided, verify the upgrade availability from the vendor's official distribution channels.
