GridFS data disclosure and deletion via query-operator injection in file IDs

MongoDB

CVE-2026-88036 · Published Sep 11, 2026

Medium6.1
Fix: upgrade to 1.30.10 or later (2 fixed versions below)
GitHub advisory

Impact

Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB C 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.

Patches

Yes. 1.30.10 or 2.5.3.

Workarounds

Validate GridFS file IDs.
