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 One of the affected actions performs no object-type check either, so arbitrary posts and pages can also be unpublished regardless of who owns them.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-2026-8976Medium
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. The nonce is leaked in the feedzyjs script.
