## Affected

- f prompts.chat: version range not reported

## Description

prompts.chat prior to commit 30a8f04 contains a server-side request forgery vulnerability in the Fal.ai media status polling feature that allows authenticated users to perform arbitrary outbound requests by supplying attacker-controlled URLs in the token parameter. Attackers can exploit the lack of URL validation to disclose the FAL_API_KEY in the Authorization header, enabling credential theft, internal network probing, and abuse of the victim's Fal.ai account.

## What to do
