WordPress Core is vulnerable to Stored Cross-Site Scripting via Quick Edit in all versions up to, and including, 7.0.2 due to insufficient escaping of user display names. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a higher privileged user accesses the affected administrative screens. This issue only affects sites with a large number of users.

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.

WordPress Core is vulnerable to Stored Cross-Site Scripting via the HTML API in various versions prior to 6.5.5 due to insufficient input sanitization and output escaping on URLs. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

WordPress Core is vulnerable to Stored Cross-Site Scripting via user display names in the Avatar block in various versions up to 6.5.2 due to insufficient output escaping on the display name. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. In addition, it also makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that have the comment block present and display the comment author's avatar.

WordPress Core is vulnerable to Sensitive Information Exposure in versions up to, and including, 6.4.3 via the redirect_guess_404_permalink function. This can allow unauthenticated attackers to expose the slug of a custom post whose 'publicly_queryable' post status has been set to 'false'.
