A vulnerability in MongoDB servers initiating outbound TLS connections can cause abnormal termination when processing malformed OCSP responses from remote peers during the TLS handshake. This occurs because OCSP stapling validation is enabled by default for outgoing TLS connections. The issue affects connections where the remote peer holds a certificate issued by the cluster's trusted certificate authority or when the connection traverses an untrusted network path.
AI Analysis
Technical Summary
CVE-2026-13070 describes a vulnerability in MongoDB servers that initiate outbound TLS connections. When the server processes a malformed OCSP response from a remote peer during the TLS handshake, it may terminate abnormally. OCSP stapling validation, enabled by default for outgoing TLS connections, is involved in this process. The vulnerability requires that the remote peer's certificate be issued by the cluster's trusted certificate authority or that the connection passes through an untrusted network path. This vulnerability is categorized under CWE-476 (NULL Pointer Dereference). There is no patch or vendor advisory provided to confirm remediation status.
Potential Impact
The impact is an abnormal termination of the MongoDB server during outbound TLS connections when processing malformed OCSP responses. This could lead to denial of service conditions affecting availability. There is no indication of code execution or data compromise from the provided information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, monitor for abnormal terminations related to outbound TLS connections and consider network controls to limit exposure to untrusted peers with certificates issued by the cluster's trusted CA.
