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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
