A MongoDB server initiating an outbound TLS connection may terminate abnormally when processing a malformed OCSP response from a remote peer during the TLS handshake.

MEDIUM 6.0EPSS 0.13%

Does this matter?

Lower severity and a low EPSS score (0.13%). Track it; it rarely justifies an emergency change on its own.

Description

A MongoDB server initiating an outbound TLS connection may terminate abnormally when processing a malformed OCSP response from a remote peer during the TLS handshake. OCSP stapling validation is enabled by default for outgoing TLS connections. Affected scenarios require the remote peer to hold a certificate issued by the cluster's trusted certificate authority, or for the connection to traverse an untrusted network path.
