Low risk26th percentile - higher than 26% of all known CVEs
Summary
The MongoDB Rust Driver does not neutralize special characters in a caller-supplied target identifier before embedding it in the request it sends to the server. An actor able to influence that identifier may cause write operations to be applied to an unintended target within the same deployment.
Risk Assessment
This may result in unauthorized modification of data belonging to another logical boundary enforced by the application, compromising data integrity and confidentiality.
Recommendation
Upgrade the MongoDB Rust Driver to a patched version. Sanitize and validate user-supplied target identifiers before use.
Other vulnerabilities in MongoDB Rust Driver
See all- CVE-2026-120673Medium
A component of the MongoDB Rust Driver that records diagnostic tracing data can capture command content before automatic client-side field level encryption is applied. In deployments that turn on the optional tracing capability together with automatic in-use encryption, a party with read access to the application's exported trace data may obtain field values that the application designated for encryption, without access to the encryption keys. This may result in unintended disclosure of data.
- CVE-2026-88024High
Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Rust 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.
- CVE-2025-11695High
When tlsInsecure=False appears in a connection string, certificate validation is disabled. This vulnerability affects MongoDB Rust Driver versions prior to v3.2.5.
Original NVD description (English source)
The MongoDB Rust Driver does not neutralize special characters in a caller-supplied target identifier before embedding it in the request it sends to the server. An actor able to influence that identifier in an application using the driver may cause write operations to be applied to an unintended target within the same deployment using the application's own credentials. This may result in unauthorized modification of data belonging to another logical boundary enforced by the application.
