CVE-2026-81526
MediumCVSS 6.5Exploitation Probability (EPSS)
Low risk10th percentile - higher than 10% 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.
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.
