What it is
MongoDB Database Tools mongofiles uses a database-stored GridFS filename as the output destination for get_id when --local is not specified. A user who can modify the file metadata can set the stored filename to ‘-’, causing a later authorized retrieval to write the file contents to standard output instead of a local file. If standard output is captured in a location accessible to that user, this may disclose GridFS content the user cannot read directly. Exploitation requires a higher-privileged operator to retrieve the affected file without an explicit local destination and attacker access to the captured output. This issue affects MongoDB Database Tools from version 3.1.4 through versions before 100.20.1.
Description quoted from the CVE record (assigned by mongodb, published 2026-11-03).
