## Summary

AxonHub (through version 1.0.0-beta11) is affected by a privilege escalation flaw in which project users can create service account API keys with system-level permissions that are never checked. This lets an attacker with basic key-creation rights read sensitive configuration data for every channel, including base URLs and model lists.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- looplj AxonHub: through 1.0.0-beta11

## Description

AxonHub through 1.0.0-beta11 contains a privilege escalation vulnerability that allows project users to assign system-level scopes by creating service_account API keys with unvalidated scopes. Attackers holding write_api_keys can mint keys with read_channels and query /admin/graphql to read every channel's configuration, including base URLs and model lists.
