CVE-2026-88029: GridFS data disclosure and deletion via query-operator injection in file IDs in the MongoDB Python Driver
- Severity: high (CVSS 8.3 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.3% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-09-10 · updated 2026-09-29
- Weakness: CWE-943
Description
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.
Affected products
- MongoDB Python Driver: from 1.6 before 4.18.1 — fixed in 4.18.1
How to fix
Upgrade to a fixed version: MongoDB Python Driver 4.18.1. Check the vendor advisory for mitigations.
