Contributor-level message deletion via unchecked ID

Published Oct 3, 2026 · Updated Oct 3, 2026

Missing authorization in Nelio Content 4.5.0 and earlier allows remote authenticated users to delete reusable social messages through WordPress. The reusable-message deletion path accepts a supplied message ID without confirming that the caller may delete the referenced nc_reusable_social post.
