MongoDB Server: missing authorization
Medium6.3CVE-2026-13078 · Published Jul 22, 2026 · updated Aug 18, 2026
A vulnerability was discovered in MongoDB Server where the server-side MozJS scripting engine unconditionally registered a module loading hook that enables JavaScript calls to read arbitrary files from the host filesystem using the mongod process's privileges. An authenticated user could exploit this through crafted aggregation pipeline commands to read sensitive files accessible to the MongoDB server process.
