CVE-2026-13070 Details
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.
A denial-of-service vulnerability has been identified in MongoDB servers that initiate outbound TLS connections. The issue arises when the server processes a malformed OCSP response from a remote peer during the TLS handshake, leading to an abnormal termination of the connection. This vulnerability occurs when OCSP stapling validation is enabled, which is the default setting for outgoing TLS connections. Affected scenarios require the remote peer to present a certificate issued by the cluster's trusted certificate authority or for the connection to traverse an untrusted network path.
Users can upgrade to MongoDB versions 8.2.12, 8.0.28, 7.0.39, or 8.3.7 to address this vulnerability.
