CVE-2026-81527: Mongodb Linq Implied Operation Unvalidated Keycve-2026-81527-mongodb-linq-implied-operation-unvalidated-key

Equality filter optimization simplifies explicit comparison to implied equality without validating that document values do not contain '$'-prefixed keys. This allows MongoDB to interpret user-supplied keys as query operators, leading to NoSQL query injection.
