## Affected

- Linuxfabrik monitoring-plugins: through 6.0.0

## Description

Linuxfabrik monitoring-plugins provides Python monitoring plugins for Icinga, Nagios, and related monitoring systems. In 6.0.0 and earlier, the redfish-* plugins built request URLs by concatenating an operator-supplied base URL with response-supplied @odata.id links, allowing a malicious or compromised BMC to redirect authenticated Redfish requests and disclose X-Auth-Token or HTTP Basic credentials.
