CVE-2026-88033
Description
A flaw was found in the GridFS component of the MongoDB Java 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 can exploit this to obtain stored file content beyond the intended target, leading to data disclosure, or cause all GridFS file chunks to be removed, resulting in a denial of service. Additionally, this flaw may allow an attacker to rename a stored file other than the intended target.
Statement
This is an Important vulnerability in the MongoDB Java Driver's GridFS component. An authenticated attacker can exploit improper handling of caller-supplied file identifiers to perform query-operator injection. This could lead to unauthorized access to GridFS file content or a denial of service by deleting file chunks, impacting data confidentiality and availability in Red Hat products that utilize this driver. The impact is significant due to the potential for data loss or exposure without requiring elevated privileges.
Mitigation
Mitigation for this issue involves ensuring that applications using the MongoDB Java Driver's GridFS component rigorously validate and sanitize all user-supplied input intended for file identifiers. Restricting access to such applications to only trusted users can further reduce the attack surface.
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.

Understanding the Weakness (CWE)
Access Control
Technical Impact: Bypass Protection Mechanism
In some cases, injectable code controls authentication; this may lead to a remote vulnerability.
Access Control
Technical Impact: Gain Privileges or Assume Identity
Injected code can access resources that the attacker is directly prevented from accessing.
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
When a product allows a user's input to contain code syntax, it might be possible for an attacker to craft the code in such a way that it will alter the intended control flow of the product. As a result, code injection can often result in the execution of arbitrary code. Code injection attacks can also lead to loss of data integrity in nearly all cases, since the control-plane data injected is always incidental to data recall or writing.
Non-Repudiation
Technical Impact: Hide Activities
Often the actions performed by injected control code are unlogged.
