 "title": "PowerPress Podcasting plugin by Blubrry <= 11.18.2 - Cross-Site Request Forgery to Onboarding Settings Update",
 "description": "The PowerPress Podcasting plugin by Blubrry plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 11.18.2 due to missing nonce validation on the onboarding show basics form handler, which also saved arbitrary submitted keys into the feed settings. This makes it possible for unauthenticated attackers to update the podcast feed settings and upload the program image via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.",
