Vulnerability description

DayBreach CVE AI Research

CVE-2026-96747 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

The client-side field level encryption support in the MongoDB Python Driver can treat a key management endpoint value ending in ".sock" as a local Unix domain socket path rather than a remote host. A user with write access to the encryption key metadata stored in the database can cause an application using the driver to open connections to local sockets on the application host. Data sent over these connections is limited to the start of a TLS handshake, so no chosen content is transmitted.
