In affected versions of WordPress, when uploading themes, the name of the theme folder can be crafted in a way that could lead to JavaScript execution in /wp-admin on the themes page. This does require an admin to upload the theme, and is low severity self-XSS. This has been patched in version 5.4.2, along with all the previously affected versions via a minor release (5.3.4, 5.2.7, 5.1.6, 5.0.10, 4.9.15, 4.8.14, 4.7.18, 4.6.19, 4.5.22, 4.4.23, 4.3.24, 4.2.28, 4.1.31, 4.0.31, 3.9.32, 3.8.34, 3.7.34).
In affected versions of WordPress, users with low privileges (like contributors and authors) can use the embed block in a certain way to inject unfiltered HTML in the block editor. When affected posts are viewed by a higher privileged user, this could lead to script execution in the editor/wp-admin. This has been patched in version 5.4.2, along with all the previously affected versions via a minor release (5.3.4, 5.2.7, 5.1.6, 5.0.10, 4.9.15, 4.8.14, 4.7.18, 4.6.19, 4.5.22, 4.4.23, 4.3.24, 4.2.28, 4.1.31, 4.0.31, 3.9.32, 3.8.34, 3.7.34).
Cross-site scripting vulnerability in WordPress versions prior to 6.0.3 allows a remote unauthenticated attacker to inject an arbitrary script. The developer also provides new patched releases for all versions since 3.7.
Auth. Stored (contributor+) Cross-Site Scripting (XSS) vulnerability in WordPress core 6.3 through 6.3.1, from 6.2 through 6.2.2, from 6.1 through 6.1.3, from 6.0 through 6.0.5, from 5.9 through 5.9.7 and Gutenberg plugin <= 16.8.0 versions.
WordPress before 5.2.4 is vulnerable to stored XSS (cross-site scripting) via the Customizer.
WordPress before 5.2.3 allows XSS in post previews by authenticated users.
WordPress users with lower privileges (like contributors) can inject JavaScript code in the block editor using a specific payload, which is executed within the dashboard. This can lead to XSS if an admin opens the post in the editor. Execution of this attack does require an authenticated user. This has been patched in WordPress 5.3.1, along with all the previous WordPress versions from 3.7 to 5.3 via a minor release. Automatic updates are enabled by default for minor releases and we strongly recommend that you keep them enabled.
Cross-site scripting (XSS) vulnerability in wp-comments-post.php in WordPress 3.3.x before 3.3.1, when Internet Explorer is used, allows remote attackers to inject arbitrary web script or HTML via the query string in a POST operation that is not properly handled by the "Duplicate comment detected" feature.

In WordPress before 4.9.9 and 5.x before 5.0.1, contributors could modify new comments made by users with greater privileges, possibly causing XSS.
In WordPress before 4.9.9 and 5.x before 5.0.1, when the Apache HTTP Server is used, authors could upload crafted files that bypass intended MIME type restrictions, leading to XSS, as demonstrated by a .jpg file without JPEG data.
In WordPress before 4.7.5, there is improper handling of post meta data values in the XML-RPC API.
In WordPress before 4.7.3 (wp-includes/embed.php), there is authenticated Cross-Site Scripting (XSS) in YouTube URL Embeds.
In WordPress before 4.7.3, there is authenticated Cross-Site Scripting (XSS) via Media File Metadata. This is demonstrated by both (1) mishandling of the playlist shortcode in the wp_playlist_shortcode function in wp-includes/media.php and (2) mishandling of meta information in the renderTracks function in wp-includes/js/mediaelement/wp-playlist.js.
WordPress is a free and open-source content management system written in PHP and paired with a MySQL or MariaDB database. ### Impact The issue allows an authenticated but low-privileged user (like contributor/author) to execute XSS in the editor. This bypasses the restrictions imposed on users who do not have the permission to post `unfiltered_html`. ### Patches This has been patched in WordPress 5.8, and will be pushed to older versions via minor releases (automatic updates). It's strongly recommended that you keep auto-updates enabled to receive the fix. ### References https://wordpress.org/news/category/releases/ https://hackerone.com/reports/1142140 ### For more information If you have any questions or comments about this advisory: * Open an issue in [HackerOne](https://hackerone.com/wordpress)
