A path traversal flaw in Grafana, the open-source monitoring and observability platform, affects versions 8.0.0-beta1 through 8.3.0 excluding the patched releases, through the public plugins path /public/plugins/<plugin-id>/ where a crafted plugin ID value allows the path to escape its intended directory. An unauthenticated remote attacker who can send HTTP requests to a vulnerable Grafana instance can read arbitrary local files on the server, with no user interaction or authentication required.

Grafana is an open-source platform for monitoring and observability. Grafana versions 8.0.0-beta1 through 8.3.0 (except for patched versions) iss vulnerable to directory traversal, allowing access to local files. The vulnerable URL path is: `<grafana_host_url>/public/plugins//`, where is the plugin ID for any installed plugin. At no time has Grafana Cloud been vulnerable. Users are advised to upgrade to patched versions 8.0.7, 8.1.8, 8.2.7, or 8.3.1. The GitHub Security Advisory contains more information about vulnerable URL paths, mitigation, and the disclosure timeline.

Exploitation timelineDated milestones for a CVE: when it was disclosed, when exploit code became public, when exploitation was confirmed, and when threat reports named it.
First seen exploited 24 months after disclosure. Public exploit code (Metasploit) was available 5 days before disclosure.
CISA KEV listing is when exploitation was confirmed, not necessarily the first attack.
