Doc Text:
A flaw was found in the GridFS component of the MongoDB Ruby Driver. Improper neutralization of special elements in data query logic can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than 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, leading to data disclosure. Additionally, this flaw could allow an attacker to cause all GridFS file chunks in the affected bucket to be removed, resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-09-10 18:11:32 UTC
Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Ruby 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.
