MediumCVSS 5.5Exploitation Probability (EPSS)
Low risk8th percentile - higher than 8% of all known CVEs
Summary
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 One of the affected actions performs no object-type check either, so arbitrary posts and pages can also be unpublished regardless of who owns them.
Risk Assessment
A user with elevated privileges can delete or hide other users' content, leading to data loss and disruption of the site.
Recommendation
Update the plugin to version 5.2.6 or later and restrict user permissions to manage import jobs.
