CVE-2026-13070

MEDIUM

Improper Validation of OCSP Response During Outbound TLS Handshake Leading to Process Termination

Title source: cna

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.
