## Technical details

The vulnerability exists in route_mapper/account.lua where the `get_user_privilege` function returns a complete nine-privilege set for pseudo-identities in the `special_users` group, including the SNMPv1_v2c pseudo-user. An authenticated low-privilege SNMP caller can exploit this misconfiguration to invoke mapped backend operations with administrative privileges, bypassing intended access controls.
