Upstream source description

The Rank Math SEO WordPress plugin before 1.0.277 does not verify that a user is allowed to edit the object being modified before updating its SEO indexing metadata, allowing users with the Author role and above to alter that metadata on content, taxonomy terms and user profiles they do not own, and to remove other users' content from the site's sitemap and search engine index.
