A flaw was found in Grafana Loki that could allow a remote attacker to traverse directories on the system, caused by improper input validation by the X-Scope-OrgID header value. An attacker could send a specially-crafted URL request containing “dot dot” sequences (/…/) to view some of the contents in the error message.
