CVE-2026-82068: Persistent Fatal Assertion Crash in MongoDB Server via Crafted Retryable Write Commands Leads to Denial of Service
A security issue in MongoDB Server allows an authenticated user with write privileges to trigger a persistent fatal assertion crash by sending specially crafted retryable write commands. The crash state is durably persisted, causing the server process to repeatedly crash on restart and potentially propagating to additional nodes in a sharded cluster. Manual intervention is required to restore service availability.

Frequently Asked Questions
Who can trigger this issue?
An authenticated user with write privileges can trigger it by sending specially crafted retryable write commands. The provided data does not indicate that unauthenticated users can exploit it.
Can restarting the affected server restore service?
No. The crash state is durably persisted, so the server can repeatedly crash after restart. Manual intervention is required to restore availability.
Could this affect more than one node?
Yes. In a sharded cluster, the persistent crash state can potentially propagate to additional nodes.
