CVE-2026-81530
Last modified
CVE-2026-81530 is a medium-severity vulnerability rated 5.6/10 on the CVSS scale. A weakness in the client-side encryption configuration surface of the MongoDB C# Driver causes sensitive key-management credential material supplied by the application to be reproduced verbatim in the driver's human-readable diagnostic representation of its client settings, instead of being masked as other secret fields are. A party able to read the application's logs, diagnostic output, or a process memory dump may thereby recover the plaintext credentials and use them to decrypt protected field data.. EPSS estimates a 0.07% chance of exploitation in the next 30 days.
