Doc Text:	A flaw was found in the Tempo and Loki datasource plugins. 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.

Description OSIDB Bzimport 2026-06-22 14:02:23 UTC

The Tempo and Loki datasource plugins construct backend HTTP requests by interpolating user-supplied input into URL paths without sanitization, enabling path traversal. A Viewer-role user can: (1) capture admin-configured datasource credentials (secureJsonData custom headers) by traversing to an attacker-controlled endpoint, (2) invoke state-changing admin endpoints on Tempo (e.g. /flush, /shutdown), and (3) exfiltrate internal service data via Loki's CallResource which returns full HTTP response bodies.
