# Pig: missing authorization exposes OAuth2 client secrets to any logged-in user

Link for people: https://infrastack.ai/live/CVE-2026-125377 (this .md is for agents)

Pig before 4.1.2 has a missing authorization check in SysClientController, so any authenticated user without client-management permission can read OAuth2 client secrets through GET /client/{clientId} and GET /client/export. An attacker who gets those secrets can request tokens for the affected clients using their configured grant types.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Look for the `SysClientController` class and the `/client/{clientId}` and `/client/export` routes in the Pig deployment.
- Check the Pig version in the project's dependency file; versions below `4.1.2` are affected.

## Fix

- Pig: upgrade to `4.1.2` or later.

- [fix] Release notes: github.com https://github.com/pig-mesh/pig/releases/tag/v4.1.2

## From the sources

Pig before 4.1.2 contains a missing authorization vulnerability in SysClientController that allows authenticated users without client-management permission to retrieve OAuth2 client secrets via GET /client/{clientId} and GET /client/export. Attackers can fetch clientSecret values for seed clients like pig, app, and daemon or export the client table, then obtain tokens using those clients' configured grant types.
