Detailsinfo

A vulnerability was found in MobSF up to 4.5.0. It has been declared as problematic. Affected by this vulnerability is the function get_browsable_activities of the file mobsf/StaticAnalyzer/views/android/manifest_analysis.py of the component Android Manifest Analysis. The manipulation with an unknown input leads to a dns rebinding vulnerability. The CWE definition for the vulnerability is CWE-350. The product performs reverse DNS resolution on an IP address to obtain the hostname and make a security decision, but it does not properly ensure that the IP address is truly associated with the hostname. As an impact it is known to affect confidentiality. The summary by CVE is:

MobSF is a mobile application security testing tool used. Prior to 4.5.1, get_browsable_activities in mobsf/StaticAnalyzer/views/android/manifest_analysis.py validates only an Android manifest android:host value with valid_host before appending a separately supplied android:port to the URL fetched by _check_url, allowing an authenticated user to upload a crafted APK that makes requests to an attacker-selected nonstandard port at /.well-known/assetlinks.json. With an attacker-controlled hostname and DNS rebinding between validation and the requests.get connection, the request can reach an internal service, although redirects remain disabled and the path is fixed. This issue is fixed in version 4.5.1.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-68927 since 07/31/2026. The exploitation appears to be easy. The attack can be launched remotely.
