Threats Tagged 'cve-2026-93393'

A heap-based buffer overflow vulnerability exists in the TLS transport layer of the MongoDB C Driver when it is built using the Windows platform TLS backend. This flaw allows a remote endpoint or an attacker capable of impersonating or redirecting the client's connection to cause out-of-bounds writes during encrypted traffic processing. Exploitation requires no authentication or user interaction and may result in memory corruption, disclosure of adjacent heap memory, or process termination.

A heap-based buffer overflow exists in the TLS transport layer of the MongoDB C Driver when built with the Windows platform TLS backend. A remote endpoint that the client connects to, or an attacker able to impersonate or redirect the client's connection, can cause the driver to write attacker-supplied data outside the bounds of a heap allocation while processing incoming encrypted traffic. No authentication or user interaction is required, because the affected processing occurs before any application-level authentication completes. Successful exploitation may lead to memory corruption in the client process, disclosure of adjacent heap memory, or termination of the process.
