Agnai is an artificial-intelligence-agnostic multi-user, mult-bot roleplaying chat system. A vulnerability in versions prior to 1.0.330 permits attackers to read arbitrary JSON files at attacker-chosen locations on the server. This issue can lead to unauthorized access to sensitive information and exposure of confidential configuration files. This only affects installations with `JSON_STORAGE` enabled which is intended to local/self-hosting only. Version 1.0.330 fixes this issue.

### CVSSv3.1 4.3 - Medium CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N

### Summary

A vulnerability has been discovered in **Agnai** that permits attackers to read arbitrary JSON files at attacker-chosen locations on the server. This issue can lead to unauthorized access to sensitive information and exposure of confidential configuration files. **This only affects installations with `JSON_STORAGE` enabled which is intended to local/self-hosting only.**

### Details & PoC

This is a path traversal vulnerability. An attacker can exploit this vulnerability by sending a specially crafted request:

```tsx GET /api/json/messages/%2e%2e%2f%2e%2e%2f%2e%2e%2f%2e%2e%2f%61%70%70%2fpackage HTTP/1.1 ```

In this example, the attacker retrieves the `package.json` file content from the server by manipulating the file path.

The request is processed by the `loadMessages` handler in `agnai/srv/api/json/index.ts` and a file is read and returned to the client. The read filename is constructed using string interpolation, with no guard or check for path traversal: https://github.com/agnaistic/agnai/blob/2b878b7ca66471c5dd080197ad9ca2f7f0022655/srv/api/json/index.ts#L77

#### Constraints
