CVE-2026-82056 — Race Condition in MongoDB Server Text Index Query Parsing Leads to Heap Use-After-Free and Denial of Service

CVE-2026-82056

Race Condition in MongoDB Server Text Index Query Parsing Leads to Heap Use-After-Free and Denial of Service PUBLISHED

Description (CNA)

A race condition in MongoDB server's 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.
