Vulnerability from github – Published: 2026-06-22 15:30 – Updated: 2026-06-22 15:30

Details

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.

Severity

5.4 (Medium)
