Vulnerabilities

fastify-http-proxy is an npm package which is a fastify plugin for proxying your http requests to another server, with hooks. By crafting a specific URL, it is possible to escape the prefix of the proxied backend service. If the base url of the proxied server is `/pub/`, a user expect that accessing `/priv` on the target service would not be possible. In affected versions, it is possible. This is fixed in version 4.3.1.

Http-proxy is a proxying library. Because of the way errors are handled in versions before 0.7.0, an attacker that forces an error can crash the server, causing a denial of service.
