CVE-2025-46730Public exploitNetwork attack vector

Authenticated service disruption via unbounded ZIP extraction

Published May 5, 2025 · Updated May 5, 2025

Resource exhaustion in MobSF 4.3.2 and earlier allows remote authenticated users to interrupt service by uploading a crafted ZIP file. The shared unzip function extracts archive entries without first limiting their cumulative uncompressed size, allowing a small upload to expand until storage is exhausted. The web interface or API must be reachable with valid credentials; extraction can disrupt MobSF and other services sharing the host.
