  "title": "Race Condition in MongoDB Server Text Index Query Parsing Leads to Heap Use-After-Free and Denial of Service",
  "description": "A race condition in MongoDB server\u0027s text index query parsing can cause a heap use-after-free read when handling upsert retry paths. Under certain concurrent index lifecycle operations, a raw pointer to internal text index metadata may be dereferenced after the underlying structures have been freed, leading to a server crash. An authenticated user with readWrite privileges can trigger this condition through specific concurrent text-search and index management operations, resulting in denial of service for all connected clients.
