CVE-2026-15286Network attack vector

Contributor-level post publication via overbroad capability check

Published Jul 10, 2026 · Updated Jul 10, 2026

Incorrect authorization in StellarWP Kadence Blocks 3.5.32 and earlier allows remote authenticated users to publish arbitrary posts. The process_pattern REST endpoint reuses get_items_permission_check, which treats the edit_posts capability as sufficient authorization for an operation that publishes content. Contributor access is sufficient to create and immediately publish posts or pages, bypassing the administrator review workflow.
