PatchTheCVECVE-2026-119179: A flaw in the connection management layer of the MongoDB Node.js driver can leave a pooled network connection
CVE-2026-119179 is a high-severity flaw (CVSS 7.0) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
A flaw in the connection management layer of the MongoDB Node.js driver can leave a pooled network connection in the pool for reuse while data from an earlier operation is still outstanding on it. In applications that enable an optional client-side operation timeout, an unauthenticated party that can send ordinary requests to the application may cause database replies to be paired with the wrong requests. This may result in unintended disclosure
