What is CVE-2026-82068?

A vulnerability present in MongoDB Server allows authenticated users with write privileges to execute specially crafted retryable write commands. This action can provoke a persistent fatal assertion crash within the server, which leads to continuous failures upon restart. The crash state is retained durably, which may cause the process to crash repeatedly, affecting additional nodes if operating within a sharded cluster. To mitigate this issue and restore service availability, manual intervention is necessary.

Affected Version(s)

MongoDB Server 8.3.0 < 8.3.9

MongoDB Server 8.0.0 < 8.0.30

MongoDB Server 7.0.0 < 7.0.41
