Doc Text:
A flaw was found in the GridFS component of the MongoDB Python Driver (pymongo). The driver can treat a caller-supplied structured file identifier as a MongoDB query condition instead of a literal identifier. An authenticated user who can influence the identifier passed to GridFS download, delete, or rename operations may retrieve stored file content beyond the intended target, delete all GridFS chunks in the affected bucket (rendering stored files unreadable), or rename a file other than the intended target.

Description OSIDB Bzimport 2026-09-10 18:12:33 UTC 
Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Python Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable. The affected rename operation may also rename a stored file other than the intended target.
