CVE-2026-82070

HIGH 7.1 ALL-YEARS

Published 2026-09-08 · Last modified 2026-09-08 · mongodb · NVD: Analyzed

A security issue in MongoDB Server's diagnostic reporting interface allows an authenticated user with monitoring privileges to access insufficiently protected credentials from concurrent administrative operations. The same credentials are properly redacted in server log output, but the diagnostic interface omits equivalent redaction. Successful exploitation requires a valid authenticated session with monitoring-level permissions and results in exposure of cleartext credentials that could enable impersonation of other users, including privileged accounts.
