Vulnerability from github – Published: 2026-08-10 09:31 – Updated: 2026-08-11 21:32

Details

The RSS Aggregator by Feedzy WordPress plugin before 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 One of the affected actions performs no object-type check either, so arbitrary posts and pages can also be unpublished regardless of who owns them.

Severity

5.5 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:H/A:N
