CVE-2023-50258
Medusa is an automatic video library manager for TV shows.
Impact
Medusa is an automatic video library manager for TV shows. Versions prior to 1.0.19 are vulnerable to unauthenticated blind server-side request forgery (SSRF). The `testDiscord` request handler in `medusa/server/web/home/handler.py` does not validate the user-controlled `discord_webhook` variable and passes it to the `notifiers.discord_notifier.test_notify` method, then `_notify_discord` and finally `_send_discord_msg` method, which sends a POST request to the user-controlled URL on line 64 in `/medusa/notifiers/discord.py`, which leads to a blind server-side request forgery. This issue allows for crafting POST requests on behalf of the Medusa server. Version 1.0.19 contains a fix for the issue.
