Grafana versions 8.0-8.3 have a flaw that allows attackers to access files on the server by manipulating the plugin URL path. This bypasses normal access controls and could expose sensitive data like configuration files or credentials.
Path traversal vulnerability in Grafana's public plugin endpoint allows unauthenticated attackers to read arbitrary files via directory traversal sequences in the plugin ID parameter. The vulnerability affects versions 8.0.0-beta1 through 8.3.0 (excluding patched releases) and requires only network access to the vulnerable endpoint.
