CVE-2026-18710 PUBLISHED

Cleartext Storage of Sensitive Information in MongoDB Driver Logging During Client Initialization

Assigner: mongodb
Reserved: 03.08.2026 Published: 11.08.2026 Updated: 11.08.2026

A MongoDB driver component could write sensitive configuration information, including a credential used for outbound network connectivity, to application log output in cleartext during routine client initialization. This occurs automatically as part of normal operation and requires no special privileges to trigger. A party able to read the affected application's logs or downstream log-aggregation storage could recover the credential and reuse it to authenticate to the associated network infrastructure. This issue affects confidentiality only.
