What is CVE-2026-68924?
CVE-2026-68924 is a medium-severity denial of service vulnerability in Mobile-Security-Framework-MobSF, published on 18 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official 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.
Weakness: CWE-400
