CVE-2026-115930

This certificate store has the recoverable eMudhra intermediate CA certificates. This issue impacts MongoDB Shell (mongosh) versions prior to 2.14.0 and can be resolved by updating to mongosh 2.14.0 which bundles Node.js 24.22.1 or later. If mongosh is installed through npm, it uses the Node.js runtime installed on the host; update that runtime separately.
