CVE-2026-120812
Full server crash via unbounded per-operand recursion in time-series query vectorization
An issue in MongoDB Server's query processing component allows an authenticated user with read privileges to cause a denial of service. Uncontrolled recursion in an internal query compilation component can lead to stack exhaustion and server process termination when processing certain queries against time-series collections.
