CVE-2026-1195: MineAdmin JWT Token refresh data authenticity

A weakness has been identified in MineAdmin 1.x/2.x. This impacts the function refresh of the file /system/refresh of the component JWT Token Handler. This manipulation causes insufficient verification of data authenticity. It is possible to initiate the attack remotely. The attack is considered to have high complexity. The exploitability is said to be difficult. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Root Cause Analysis

The vulnerability exists in the token refresh mechanism of MineAdmin. The provided GitHub issue explicitly states that the /system/refresh endpoint is vulnerable and that the refresh method fails to validate the JWT signature. Based on the Hyperf framework's conventions, this route would be handled by a refresh method in a SystemController. Although the file could not be retrieved from the repository, the detailed description of the vulnerability in the linked issue provides strong evidence to pinpoint SystemController::refresh as the vulnerable function. The lack of signature validation in a token refresh mechanism is a critical security flaw that allows for privilege escalation.

Vulnerable functions

SystemController::refresh

app/System/Controller/SystemController.php

This function is responsible for refreshing JWT tokens. The vulnerability exists because the function does not verify the signature of the token being refreshed. An attacker can provide a forged token with a valid structure but a modified payload (e.g., with a different user ID) and a new signature. The `refresh` function would then issue a new, valid token based on the forged claims, effectively allowing the attacker to impersonate any user.
