Summary
Cross-session PubSub topic injection via URL parameter in phoenix_storybook
Details

Authorization Bypass Through User-Controlled Key vulnerability in phenixdigital phoenix_storybook allows cross-session PubSub topic injection via a URL query parameter.

'Elixir.PhoenixStorybook.Story.ComponentIframeLive':handleparams/3 in lib/phoenixstorybook/live/story/componentiframelive.ex reads a PubSub topic directly from params["topic"] and broadcasts {:componentiframepid, self()} on it with no check that the topic belongs to the requesting session. The shared PhoenixStorybook.PubSub is used to coordinate playground LiveViews with their iframes: a playground subscribes to a session-specific topic and uses the received iframe pid to direct subsequent control messages (variation state, theme switches, extra-assign payloads) via send/2. Because the iframe trusts the query parameter, an attacker who loads /storybook/iframe/<story>?topic=<victim_topic> causes their iframe process pid to be announced on the victim's topic. The victim's playground then addresses its private messages to the attacker's iframe process.

This issue affects phoenix_storybook from 0.4.0 before 1.1.0.
