Summary
The RSS Aggregator by Feedzy plugin for WordPress up to version 5.1.7 contains an authorization bypass vulnerability. Lack of permission verification allows users with Contributor access and above to create and execute RSS import jobs, delete posts, clear error logs, and enumerate taxonomy terms and meta keys. The nonce is leaked in the feedzyjs script.
Risk Assessment
An attacker can perform unauthorized import and deletion operations, potentially leading to data loss, content manipulation, and site integrity compromise.
Recommendation
Immediately update the RSS Aggregator by Feedzy plugin to the latest version and review user permissions.
Other vulnerabilities in RSS Aggregator by Feedzy
See all- CVE-2026-18934Medium
The RSS Aggregator by Feedzy plugin before version 5.2.6 does not verify that the requesting user owns or is allowed to edit the import job named in the request, allowing users with author-level access and above to permanently delete the posts created by another user's import job, reset its deduplication and scheduling state, disable it, or clear its error log. One of the affected actions performs no object-type check either, so arbitrary posts and pages can also be unpublished regardless of who owns them.
- CVE-2026-13252Medium
The RSS Aggregator by Feedzy plugin for WordPress up to version 5.2.1 is vulnerable to stored XSS via the 'aspectRatio' attribute due to insufficient input sanitization and output escaping. Authenticated attackers with contributor-level access or higher can inject arbitrary scripts that execute when users access affected pages.
Original NVD description (English source)
The RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 5.1.7. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to create and execute RSS import jobs, purge (force-delete) all posts associated with any import job, clear import error logs, and enumerate taxonomy terms and post meta_key names. The nonce required to reach these sub-handlers is leaked to any user with the edit_posts capability via the feedzyjs localized script injected into the block editor, meaning no privileged nonce theft or separate exploit step is required for Contributor-level users.
