WPGraphQL before 2.24.1 contains a missing authorization vulnerability in the createComment mutation that allows unauthenticated attackers to comment on non-public posts by bypassing post status checks. Attackers can attach comments to draft, private, trashed, or password-protected posts to leak hidden titles via moderator notifications, enumerate post IDs, and backdate comments or mark them as pingbacks.
