Walkthrough

The change moves NoSQL injection database seeding into a dedicated seeder, runs it during bootstrap, exposes MongoDB connection accessors, and assigns vulnerability hint types by level.

Changes

NoSQL injection flow

Layer / File(s) Summary
MongoDB connection contract
src/Mongo/MongoConnection.php
MongoConnection no longer seeds during findOne. The class now exposes manager(), database(), and namespace().
Level-specific vulnerability hints
src/NoSQLInjectionVulnerability/NoSQLInjection.php
The vulnerability definition includes NoSQL injection and weak credential storage types. LEVEL_4 receives weak credential storage types; other levels receive NoSQL injection types.
Dedicated MongoDB seeding
src/NoSQLInjectionVulnerability/NoSQLInjectionSeeder.php, src/framework/Bootstrap.php
NoSQLInjectionSeeder creates indexed users and seed metadata. Bootstrap invokes the seeder before registering vulnerability providers.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to a89f1

MongoDB outages or concurrent initialization can prevent the application from starting, including unrelated vulnerability routes. These failures should be fixed before merge.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Do not make global bootstrap depend on MongoDB seeding.

seedIfRequired() performs MongoDB operations and throws RuntimeException on failure. This call runs before any providers or routes are registered.

A transient MongoDB failure therefore prevents Bootstrap from initializing, including for vulnerability routes that do not use MongoDB. Invoke the seeder from the NoSQL injection request path, or isolate its failure from unrelated routes.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Do not update _id during an upsert.

Each $user contains a new _id. The $set operation attempts to replace the immutable _id when the user already exists.

Two concurrent seeders can both pass the metadata check. The second seeder then fails after the first seeder inserts the users. This failure aborts bootstrap and can repeat because the metadata write does not complete.

Move _id to $setOnInsert, or let MongoDB generate it.

Proposed fix
 foreach ($users as $user) {
+    $id = $user["_id"];
+    unset($user["_id"]);
     $bulkWrite->update(
         ["level" => $user["level"], "username" => $user["username"]],
-        ["$set" => $user],
+        [
+            "$set" => $user,
+            "$setOnInsert" => ["_id" => $id],
+        ],
         ["upsert" => true]
     );
