Detailsinfo

A vulnerability was found in motioneye-project motioneye up to 0.43.x. It has been classified as critical. Affected is the function get_media_preview of the file mediafiles.py. The manipulation of the argument filename with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality. CVE summarizes:

motionEye (mEye) is an online interface for motion software, which is a video surveillance program with motion detection. Versions prior to 0.44.0 are vulnerable to path traversal in the picture and movie API endpoints, suhc as /picture/{id}/preview/{filename}. Neither the API handlers, nor the mediafiles.py functions such as get_media_preview() check for .. sequences in the filename parameter, except for get_media_content(). This allows an authenticated user with normal (non-admin) privileges to read arbitrary files from the filesystem as the motionEye process user, such as: /etc/passwd, /etc/shadow, motionEye config files containing password hashes and plaintext passwords, SSH keys, and other cameras' surveillance footage. This issue has been fixed in version 0.44.0.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-31978 since 03/10/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

Upgrading to version 0.44.0 eliminates this vulnerability. The upgrade is hosted for download at github.com.
