CVE-2026-88030
Description
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).
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
