Description
The Leaky Paywall plugin for WordPress is vulnerable to Sensitive Information Exposure via the site's RSS feeds in all versions up to, and including, 5.2.1, due to content restriction only being applied on single post and page views and REST API requests, while feed content was never filtered. On sites configured to include the full text of each post in feeds (the WordPress default), this makes it possible for unauthenticated attackers to read the full content of paywalled and level-restricted posts, bypassing the paywall.
