CVE-2026-68924

MobSF: Zip Bomb Denial of Service via Per-File Size Limit Bypass in ZIP/APK Extraction

Published Aug 18, 2026 CVSS 3.1 · 4.9 Medium EPSS < 1% KEV · Not listed
Description
MobSF is a mobile application security testing tool used. Prior to 4.5.1, the unzip function in mobsf/StaticAnalyzer/views/common/shared_func.py logs that an archive member exceeding ZIP_MAX_UNCOMPRESSED_FILE_SIZE is being skipped but does not continue to the next member, so an authenticated user can upload a crafted ZIP or APK whose oversized member is extracted to disk when the aggregate ZIP_MAX_UNCOMPRESSED_TOTAL_SIZE limit has not yet been reached, potentially exhausting disk space and preventing further scans. This issue is fixed in version 4.5.1.
