In the current implementation of the server deletion endpoint (/delete-server), the delete operation is used with potentially user-provided guild_id and server_uuid values. Although these values are retrieved from req.body and are not directly user-controlled, there is a theoretical risk of prototype pollution if they were manipulated by an attacker.
Prototype pollution is a type of vulnerability where an attacker can modify the prototype of a JavaScript object, potentially causing unexpected behavior in the application.
This is a theoretical vulnerability and does not have specific reproduction steps in the current implementation.
The application should not allow prototype pollution via user-provided guild_id and server_uuid values.
The current implementation does not present a clear risk of prototype pollution, but further investigation and potential mitigation measures are warranted.
Add input validation to ensure that guild_id and server_uuid are in the expected format before they are used. For example, if these IDs should only contain alphanumeric characters, reject any values that contain other characters.
router.delete('/delete-server', async (req, res) => {
const { guild_id, server_uuid } = req.body;
// ...
// Delete server_uuid
if (serverInfoData[guild_id]) {
delete serverInfoData[guild_id][server_uuid];
}
// ...
});

Steps to Reproduce:
This is a theoretical vulnerability and does not have specific reproduction steps in the current implementation.
Expected Outcome:
The application should not allow prototype pollution via user-provided guild_id and server_uuid values.
Actual Outcome:
The current implementation does not present a clear risk of prototype pollution, but further investigation and potential mitigation measures are warranted.
Suggested Fix:
Add input validation to ensure that guild_id and server_uuid are in the expected format before they are used. For example, if these IDs should only contain alphanumeric characters, reject any values that contain other characters.
