Dist Ubuntu Esm H88
Ubuntu alerts users that Prometheus Alertmanager may reveal confidential data, posing a threat to the integrity and privacy of systems.
prometheus-alertmanager could be made to expose sensitive information over the network.

Summary

prometheus-alertmanager could be made to expose sensitive information over

the network.

Software Description:

- prometheus-alertmanager: handle and deliver alerts created by Prometheus

Details:

It was discovered that prometheus-alertmanager didn't properly sanitize

input it received through an API endpoint. An attacker with permission to

send requests to this endpoint could potentially inject arbitrary code.

On Ubuntu 20.04 LTS and Ubuntu 22.04 LTS, this vulnerability is only

present if the UI has been explicitly activated.

The problem can be corrected by updating your system to the following
package versions:
