CVE ID :CVE-2026-81518
Published : Aug. 28, 2026, 10:16 p.m. | 13 minutes ago
Description :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.
Severity: 8.7 | HIGH
