+# Unnecessary admin parameter
+
+## Description 
+
+- Category: `Access control`
+- Severity: `Medium`
+- Detector: [`unnecessary-admin-parameter`](https://github.com/CoinFabrik/scout-soroban/tree/main/detectors/unnecessary-admin-parameter)
+- Test Cases: [`unnecessary-admin-parameter-1`](https://github.com/CoinFabrik/scout-soroban/tree/main/test-cases/unnecessary-admin-parameter/unnecessary-admin-parameter-1)
+
+In rust, a bad practice would be passing variables with names similar to "admin" as parameters that are used in `require_auth` calls within the functions of the contract. Ideally, the admin information should be retrieved directly from storage to avoid security issues in the contract.
+
+## Why is this bad? 
+
+Passing admin information as parameters can cause security issues, as the variable could be manipulated, resulting in incorrect authentication verification.
+
+## Issue example 
+
+Consider the following `Soroban` contract:
+
+```rust
+
+  pub fn set_admin(env: Env, new_admin: Address, admin: Address) {
+        admin.require_auth();
+        env.storage().instance().set(&DataKey::Admin, &new_admin);
+    }
+
+```
+
+In this example the admin is being passed as a parameter and then validated with `require_auth`.
+
+The code example can be found [here](https://github.com/CoinFabrik/scout-soroban/tree/main/test-cases/unnecessary-admin-parameter/unnecessary-admin-parameter-1/vulnerable-example).
+
+
+## Remediated example
+
+Consider the following `Soroban` contract:
+
+```rust
+
+ pub fn set_admin(env: Env, new_admin: Address) {
+        // Initialize has already set the admin, so we can retrieve it directly.
+        let current_admin: Address = env.storage().instance().get(&DataKey::Admin).unwrap();
+        current_admin.require_auth();
+        env.storage().instance().set(&DataKey::Admin, &new_admin);
+    }
+        
+```
+
+In this example, the admin information is retrieved directly from storage and then validated with `require_auth`.
+
+The remediated code example can be found [here](https://github.com/CoinFabrik/scout-soroban/tree/main/test-cases/unnecessary-admin-parameter/unnecessary-admin-parameter-1/remediated-example).
+
+## How is it detected?
+
+Checks the use of function parameters with names similar to "admin."
