The export_data function of the Simple 301 Redirects by BetterLinks WordPress plugin before 2.0.4 had no capability or nonce checks making it possible for unauthenticated users to export a site's redirects.

A lack of capability checks and insufficient nonce check on the AJAX action in the Simple 301 Redirects by BetterLinks WordPress plugin before 2.0.4, made it possible for authenticated users to install arbitrary plugins on vulnerable sites.

The Funnel Builder by CartFlows – Create High Converting Sales Funnels For WordPress plugin before 1.6.13 did not sanitise its facebook_pixel_id and google_analytics_id settings, allowing high privilege users to set XSS payload in them, which will either be executed on pages generated by the plugin, or the whole website depending on the settings used.

The Listeo WordPress theme before 1.6.11 did not ensure that the Post/Page and Booking to delete belong to the user making the request, allowing any authenticated users to delete arbitrary page/post and booking via an IDOR vector.

The All in One SEO – Best WordPress SEO Plugin – Easily Improve Your SEO Rankings before 4.1.0.2 enables authenticated users with "aioseo_tools_settings" privilege (most of the time admin) to execute arbitrary code on the underlying host. Users can restore plugin's configuration by uploading a backup .ini file in the section "Tool > Import/Export". However, the plugin attempts to unserialize values of the .ini file. Moreover, the plugin embeds Monolog library which can be used to craft a gadget chain and thus trigger system command execution.

Low privileged users can use the AJAX action 'cp_plugins_do_button_job_later_callback' in the WP Maintenance Mode & Site Under Construction WordPress plugin before 1.8.2, to install any plugin (including a specific version) from the WordPress repository, as well as activate arbitrary plugin from then blog, which helps attackers install vulnerable plugins and could lead to more critical vulnerabilities like RCE.

The Kaswara Modern VC Addons WordPress plugin through 3.0.1 allows unauthenticated arbitrary file upload via the 'uploadFontIcon' AJAX action. The supplied zipfile being unzipped in the wp-content/uploads/kaswara/fonts_icon directory with no checks for malicious files such as PHP.

The Event Banner WordPress plugin through 1.3 does not verify the uploaded image file, allowing admin accounts to upload arbitrary files, such as .exe, .php, or others executable, leading to RCE. Due to the lack of CSRF check, the issue can also be used via such vector to achieve the same result, or via a LFI as authorisation checks are missing (but would require WP to be loaded)

The Realteo WordPress plugin before 1.2.4, used by the Findeo Theme, did not ensure that the requested property to be deleted belong to the user making the request, allowing any authenticated users to delete arbitrary properties by tampering with the property_id parameter.

Wordpress is an open source CMS. A user with the ability to upload files (like an Author) can exploit an XML parsing issue in the Media Library leading to XXE attacks. This requires WordPress installation to be using PHP 8. Access to internal files is possible in a successful XXE attack. This has been patched in WordPress version 5.7.1, along with the older affected versions via a minor release. We strongly recommend you keep auto-updates enabled.
