Security readout for executives and security teams
Plain-English summary
Owlfiles File Manager 12.0.1 has a path traversal flaw in its built-in HTTP server. A remote, unauthenticated attacker could read restricted system directories from the device if that server is reachable. This is mainly a confidentiality risk for devices using the affected app version.
Executive priority
Prioritize this for mobile or endpoint environments where Owlfiles is used for file sharing. The business risk is unauthorized reading of local system or sensitive files. Urgency is highest for devices exposing the app’s HTTP server beyond trusted networks.
Technical view
CVE-2022-50890 is CWE-22 path traversal in Skyjos Owlfiles File Manager 12.0.1. The CVSS 4.0 score is 8.7, with network attack vector, low complexity, no privileges, and no user interaction. Sources describe crafted GET requests enabling access to restricted system directories. Integrity and availability impact are not indicated.
Likely exposure
Exposure is most likely where Owlfiles File Manager 12.0.1 is installed and its built-in HTTP server is enabled on a reachable network. Internet exposure would increase risk. The provided sources do not identify other affected versions or platforms beyond the App Store-listed product.
Exploitation context
An ExploitDB entry is referenced, indicating public exploit information exists. The CVE is not marked in CISA KEV in the provided data, and no cited source states active exploitation. Treat reachable instances as high priority because the flaw requires no authentication or user interaction.
Researcher notes
Public data is limited to affected version 12.0.1 and path traversal behavior in the built-in HTTP server. Do not assume other versions are affected without vendor confirmation. Patch status is not provided in the supplied sources, so remediation should be anchored to vendor or App Store guidance.
Mitigation direction
- Identify installations of Owlfiles File Manager 12.0.1.
- Check Skyjos and App Store guidance for a fixed version.
- Update the app if a vendor-fixed release is available.
- Disable the built-in HTTP server if not required.
- Restrict access to trusted networks only.
- Remove the app where business need is low.
Validation and detection
- Confirm the installed Owlfiles File Manager version.
- Determine whether the built-in HTTP server is enabled.
- Check whether the service is reachable from untrusted networks.
- Review access logs for suspicious file-access requests.
- Document any internet-exposed instances for urgent remediation.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
