CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in PowerPress Podcasting plugin by Blubrry <= 11.17.9 takes no account at all. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. 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

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: PowerPress Podcasting plugin by Blubrry 11.17.11 closes this, and updating the plugin is the step that ends it.
