Description

Vvveb prior to 1.0.8.1 contains a server-side request forgery vulnerability in the oEmbedProxy action of the editor/editor module where the url parameter is passed directly to getUrl() via curl without scheme or destination validation. Authenticated backend users can supply file:// URLs to read arbitrary files readable by the web server process or http:// URLs targeting internal network addresses to probe internal services, with response bodies returned directly to the caller.
