CVE-2026-68922 MobSF CVE debrief

Who should care

Defenders responsible for mobile application security testing tools, specifically those using MobSF, should assess exposure and verify remediation. They should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. Additionally, they should plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.

Why it matters

CVE-2026-68922 is a medium-severity vulnerability in MobSF that allows authenticated users to read server files and retrieve them through a predictable endpoint. Defenders should verify MobSF version, restrict access to the /download/ endpoint, and monitor for suspicious activity.

• Authenticated users can read server files with specific suffixes
• Files can be retrieved through a predictable endpoint
• Vulnerability requires verification of MobSF version and user access controls
• Remediation involves upgrading to version 4.5.1 and restricting access to the /download/ endpoint

Technical summary

The find_icon_path_zip function in MobSF's icon_analysis.py uses the Android manifest android:icon value to construct paths under the scan resource directory without rejecting traversal or verifying containment. This allows an authenticated user to upload a crafted ZIP or APK that reads a server file with an ALLOWED_EXTENSIONS suffix, copies it to DWD_DIR as the predictable name -icon., and retrieves it through the /download/ endpoint.

Defensive priority

Medium priority for defenders to verify and remediate, as it requires authentication and has a medium CVSS score.

Recommended defensive actions

• Verify MobSF version and upgrade to 4.5.1 if necessary
• Restrict access to the /download/ endpoint
• Monitor for suspicious activity on the server
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

Evidence from the CVE record and NVD detail page indicates that the vulnerability exists in MobSF versions prior to 4.5.1 and is fixed in version 4.5.1. The find_icon_path_zip function in MobSF's icon_analysis.py uses the Android manifest android:icon value to construct paths under the scan resource directory without rejecting traversal or verifying containment. This allows an authenticated user to upload a crafted ZIP or APK that reads a server file with an ALLOWED_EXTENSIONS suffix, copies it to DWD_DIR as the predictable name -icon
