Summary
The RSS Aggregator by Feedzy plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 5.1.0 via the 'feedzy_sanitize_feeds' function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query information from internal services.
Risk Assessment
The risk is the possibility of using the server as a proxy to attack internal services, which could lead to disclosure of sensitive information or further attacks within the internal network.
Recommendation
It is recommended to update the plugin to the latest version that contains the fix. Also restrict access to the plugin to trusted users only.
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 One of the affected actions performs no object-type check either, so arbitrary posts and pages can also be unpublished regardless of who owns them.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.
- CVE-2026-8976Medium
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.
