CVE-2026-81530

Name of the Vulnerable Software and Affected Versions MongoDB C# Driver (affected versions not specified)

Description A weakness in the client-side encryption configuration surface allows sensitive key-management credential material to be reproduced verbatim in the human-readable diagnostic representation of client settings. While other secret fields are masked, these credentials remain unredacted. An attacker with access to application logs, diagnostic output, or process memory dumps could recover these plaintext credentials to decrypt protected field data.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
