Grafana directory traversal for .cvs files

Today we are releasing Grafana 8.3.2 and 7.5.12. This patch release includes a moderate severity security fix for directory traversal for arbitrary .csv files.

Although it can be difficult, ultimately it's for the overall benefit of Grafana and the community. Please know that this is a top priority for us. We are spending significant resources on this in the remainder of 2021 already, including full outside assessment. We will continue and increase…Read More
