Details

As written in the advisory (Markdown source, shown as plain text).

### Summary The fix for the "SSRF Vulnerability on assetlinks_check(act_name, well_knowns)" vulnerability could potentially be bypassed. ### Details Since the requests.get() request in the _check_url method is specified as allow_redirects=True, if "https://mydomain.com/.well-known/assetlinks.json" returns a 302 redirect, subsequent requests will be sent automatically. If the redirect location is "http://192.168.1.102/user/delete/1", a request will be sent here as well. <img width="610" alt="image" src="https://github.com/MobSF/Mobile-Security-Framework-MobSF/assets/150332295/a8c9630e-3d12-441a-816c-8f5e427a5194"> It will be safer to use allow_redirects=False. ### Impact The attacker can cause the server to make a connection to internal-only services within the organization's infrastructure.
