MEDIUMCVSS 5.5/10

Last modified

CVE-2026-120673 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.
