Medium (5.3) in grafana loki. EPSS 1.5% chance of exploitation in the next 30 days. Fixed in github.com/grafana/loki 2.3.0.
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.
