Summary
Lavish lavish-axi versions before 0.1.43 run a loopback HTTP server that does not authenticate requests or validate Host and Origin headers. A website visited while the server runs can use DNS rebinding to send same-origin requests to it, which lets the site read arbitrary files readable by the server process through an unauthenticated session route and queue text into an active agent session when an artifact path is known or guessed. An attacker needs a victim to visit the attacker-controlled website, and the flaw is tracked under CWE-346 and CWE-306.

Description from the CNA
Lavish is the new editor for your HTML artifacts. Prior to 0.1.43, the lavish-axi loopback HTTP server did not authenticate requests or validate Host and Origin values on session, artifact, prompt, and polling routes. A website visited while the server is running can use DNS rebinding to send same-origin browser requests to the local service. POST /api/sessions accepts a caller-selected file path and returns its deterministic session key; GET /artifact/:key/index.html then returns the file contents, allowing disclosure of any file readable by the server process without an existing session. An attacker can also queue text through POST /api/:key/prompts for an active agent session when the artifact path is known or guessed. Visiting the attacker-controlled website is the required user interaction. This vulnerability is fixed in 0.1.43.
