Vulnerability Overview

The PowerPress Podcasting plugin by Blubrry plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 11.17.9. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in PowerPress Podcasting plugin by Blubrry <= 11.17.9 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For PowerPress Podcasting plugin by Blubrry the fix is 11.17.11: builds <= 11.17.9 are affected, anything from 11.17.11 onward is not.

Remediation

Update to version 11.17.11, or a newer patched version
