Missing limits on resource use in the match expression evaluator of MongoDB Server can cause the server to consume excessive memory. Internal schema validation operators that are meant only for server use are accepted in user-supplied query filters. When these operators are nested and applied to documents that contain arrays, the server evaluates every combination of array elements without a sufficient limit on the resources used. This can cause memory use to grow until the mongod process runs out of memory and terminates. The behavior can occur when an authenticated user with read-only privileges runs an aggregation query that nests these operators.
No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
