Summary

A user with Viewer permissions can use specially crafted requests to the Tempo and Loki data source plugins to reach unintended backend endpoints. Depending on the backend configuration this can expose data source credentials, leak internal responses, or trigger administrative actions on the configured backend.

A remote attacker with a Viewer role could exploit a path traversal vulnerability by manipulating user-supplied input in URL paths. This could allow the attacker to capture sensitive administrator-configured datasource credentials, invoke state-changing administrative functions on Tempo, or exfiltrate internal service data from Loki.

Red Hat severity: Moderate — CVSS 5.4 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L). Weakness: CWE-22.
