Low (1.0). EPSS 0.1% estimated probability of exploitation activity in the next 30 days.

On this page
MongoDB Database Tools mongofiles does not resolve existing parent-directory symlinks when validating output paths for get_regex. An unauthorized user who can both upload a GridFS file and place a symlink in the operator's download working directory can cause a later retrieval to create a file containing unauthorized user-controlled data outside that directory, using the operator process's filesystem permissions. The issue can occur with default traversal and overwrite settings. Exploitation requires an operator to retrieve matching files from the affected working directory; the demonstrated default behavior creates a new file rather than overwriting an existing file. This issue affects MongoDB Database Tools versions 100.2.0 through versions before 100.20.1.
