- Issue
- An issue was discovered in Grafana Loki through 2.2.1. The header value X-Scope-OrgID is used to construct file paths for rules files, and if crafted to conduct directory traversal such as ae ../../sensitive/path/in/deployment pathname, then Loki will attempt to parse a rules file at that location and include some of the contents in the error message.
Recommended action: Upgrade to 2.3.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
