Hi, The following vulnerability was published for wordpress. CVE-2026-3906[0]: | 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 `create_item_permissions_check()` method in the comments | controller did not verify that the authenticated user has | `edit_post` 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
