CVE-2026-88031: MongoDB Go Driver

High severity, CVSS 8.1. EPSS: 0.5% chance of exploitation in the next 30 days.

Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Go 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 cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable.

Affected products

• MongoDB Go Driver: from 1.0.0, before 1.17.10 (fixed in 1.17.10); from 2.0.0, before 2.9.1 (fixed in 2.9.1)
