CVE-2026-81518

BI Connector Optional Client Certificate Verification Allows Unauthenticated Connections PUBLISHED

Description (CNA)

When mongosqld is configured with a client certificate authority file, the listener requests a client certificate during the TLS handshake but does not require one, so a client that presents no certificate is still accepted. In deployments that rely on client certificates as the sole means of identifying users, a remote party with network access to the listener can therefore establish a session and read the MongoDB data exposed through the connector.
