  "title": "wordpress: WordPress core is vulnerable to unauthorized access in versions 6.9 through 6.9.1",
  "description": "WordPress core is vulnerable to unauthorized access in versions 6.9 through 6.9.1. The Notes feature (block-level collaboration annotations) was introduced in WordPress 6.9 to allow editorial comments directly on posts in the block editor. However, the REST API \u0060create_item_permissions_check()\u0060 method in the comments controller did not verify that the authenticated user has \u0060edit_post\u0060 permission on the target post when creating a note. This makes it possible for authenticated attackers with Subscriber-level access to create notes on any post, including posts authored by other users, private posts, and posts in any status.",
