Detailsinfo

A vulnerability classified as critical has been found in pymedusa Medusa up to 1.0.18. This affects the function testslack of the file medusa/server/web/home/handler.py of the component POST Request Handler. The manipulation of the argument slack_webhook with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality. The summary by CVE is:

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 `testslack` request handler in `medusa/server/web/home/handler.py` does not validate the user-controlled `slack_webhook` variable and passes it to the `notifiers.slack_notifier.test_notify` method, then `_notify_slack` and finally `_send_slack` method, which sends a POST request to the user-controlled URL on line 103 in `/medusa/notifiers/slack.py`, which leads to a blind server-side request forgery (SSRF). This issue allows for crafting POST requests on behalf of the Medusa server. Version 1.0.19 contains a fix for the issue.
