The Cookie Banner for GDPR / CCPA – WPLP Cookie Consent plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'regionArray' parameter in all versions up to, and including, 4.3.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires that the site administrator has enabled the 'Support Google Consent Mode (GCM)' setting, which is disabled by default. Additionally, the AJAX handler performs no nonce or capability check, allowing any authenticated user including those with Subscriber-level access to overwrite the affected plugin setting.

The Appointment Booking Calendar — Simply Schedule Appointments Booking Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.6.12.10 via the ssapastappointments due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to access appointment records belonging to arbitrary users and harvest the per-appointment ownership tokens (32-character hashes) embedded in the rendered HTML, which can then be used without any authentication to read or modify those appointments including full customer PII such as name, email, phone number, and private notes. The /wp-json/ssa/v1/render-shortcode REST endpoint is registered unconditionally on restapiinit regardless of whether the Divi theme is installed, and its permission callback only requires currentusercan('editposts'), meaning any Contributor-level account is sufficient to trigger this entire exploit chain.

The Infility Global plugin for WordPress is vulnerable to Stored Cross-Site Scripting via /cf7record Log Endpoint in all versions up to, and including, 2.15.21 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The /cf7records viewer is accessible to any authenticated user including those with Subscriber-level access, meaning the injected payload executes for any logged-in user who visits the records page.

The Customer Support Ticket System & Helpdesk plugin for WordPress is vulnerable to Code Injection via the 'path' parameter in all versions up to, and including, 6.0.5 due to the use of dynamic function invocation on an attacker-controlled value with insufficient validation. This makes it possible for unauthenticated attackers to invoke arbitrary parameterless PHP functions, which can be used to disrupt site functionality or expose sensitive information. The required nonce is publicly emitted via wplocalizescript whenever the plugin's [emdform] shortcode is rendered on any public-facing page, making the endpoint reachable by unauthenticated visitors without any prior authentication or privilege.

The SEO Plugin by Squirrly SEO plugin for WordPress is vulnerable to Arbitrary Post Creation and Stored Cross-Site Scripting in all versions up to, and including, 14.0.0 due to a leak of an API token and insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to create arbitrary posts, and, if the Advanced Custom Fields plugin is installed and activated, inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Backstage - Customizer Demo Access plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.4.2. This is due to the plugin assigning the manageoptions capability to the backstagecustomizeruser demo role, which is more permissive than necessary for Customizer-only demo access. This makes it possible for unauthenticated attackers to navigate beyond the Customizer and update arbitrary WordPress options such as defaultrole, leading to privilege escalation.

WordPress is a free and open-source content management system written in PHP and paired with a MySQL or MariaDB database. In affected versions the widgets editor introduced in WordPress 5.8 beta 1 has improper handling of HTML input in the Custom HTML feature. This leads to stored XSS in the custom HTML widget. This has been patched in WordPress 5.8. It was only present during the testing/beta phase of WordPress 5.8.

WordPress is a free and open-source content management system written in PHP and paired with a MySQL or MariaDB database. In affected versions authenticated users who don't have permission to view private post types/data can bypass restrictions in the block editor under certain conditions. This affected WordPress 5.8 beta during the testing period. It's fixed in the final 5.8 release.

In WordPress through 4.9.2, unauthenticated attackers can cause a denial of service (resource consumption) by using the large list of registered .js files (from wp-includes/script-loader.php) to construct a series of requests to load every file many times.

WordPress before 4.9.2 has XSS in the Flash fallback files in MediaElement (under wp-includes/js/mediaelement).

In WordPress before 4.7.3 (wp-admin/js/tags-box.js), there is cross-site scripting (XSS) via taxonomy term names.

In WordPress before 4.7.3, there is cross-site request forgery (CSRF) in Press This (wp-admin/includes/class-wp-press-this.php), leading to excessive use of server resources. The CSRF can trigger an outbound HTTP request for a large file that is then parsed by Press This.

Cross-site request forgery (CSRF) vulnerability in the widget-editing accessibility-mode feature in WordPress before 4.7.1 allows remote attackers to hijack the authentication of unspecified victims for requests that perform a widgets-access action, related to wp-admin/includes/class-wp-screen.php and wp-admin/widgets.php.

Cross-site scripting (XSS) vulnerability in the theme-name fallback functionality in wp-includes/class-wp-theme.php in WordPress before 4.7.1 allows remote attackers to inject arbitrary web script or HTML via a crafted directory name of a theme, related to wp-admin/includes/class-theme-installer-skin.php.

wp-includes/ms-functions.php in the Multisite WordPress API in WordPress before 4.7.1 does not properly choose random numbers for keys, which makes it easier for remote attackers to bypass intended access restrictions via a crafted (1) site signup or (2) user signup.

wp-mail.php in WordPress before 4.7.1 might allow remote attackers to bypass intended posting restrictions via a spoofed mail server with the mail.example.com name.

Cross-site request forgery (CSRF) vulnerability in WordPress before 4.7.1 allows remote attackers to hijack the authentication of unspecified victims via vectors involving a Flash file upload.

wp-includes/rest-api/endpoints/class-wp-rest-users-controller.php in the REST API implementation in WordPress 4.7 before 4.7.1 does not properly restrict listings of post authors, which allows remote attackers to obtain sensitive information via a wp-json/wp/v2/users request.

Multiple cross-site scripting (XSS) vulnerabilities in wp-admin/update-core.php in WordPress before 4.7.1 allow remote attackers to inject arbitrary web script or HTML via the (1) name or (2) version header of a plugin.

WordPress 3.8.2 has been released and fixes the following issue:

"It also contains a fix to prevent a user with the Contributor role from improperly publishing posts. Reported by edik."

"Privilege escalation: prevent contributors from publishing posts. CVE-2014-0165."
