Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The mobsf package before 4.5.1 has a server-side request forgery flaw in its Android App Link assetlinks checker: the port restriction is applied to the host alone, so a port from the manifest is appended unchecked. An attacker who can upload or trigger analysis of a crafted APK, which requires an authenticated user, can make the server send requests to a chosen non-standard port, including internal services via DNS rebinding. Upgrade to mobsf 4.5.1 or later.
