Exploitation Status

Proof-of-concept exploit code exists

  • CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
  • CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

Description

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.

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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mobsf, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update mobsf to 3.9.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-m435-9v6r-v5f6 is resolved across your whole dependency graph.

  3. Workarounds

    Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.
