The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Themesgrove WidgetKit allows Stored XSS.This issue affects WidgetKit: from n/a through 2.5.0.

The All-in-One Addons for Elementor – WidgetKit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple pricing widgets (e.g. Pricing Single, Pricing Icon, Pricing Tab) in all versions up to, and including, 2.4.8 due to insufficient input sanitization and output escaping. 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.

The All-in-One Addons for Elementor WordPress plugin before 2.4.4 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)

The “All-in-One Addons for Elementor – WidgetKit” WordPress Plugin before 2.3.10 has several widgets that are vulnerable to stored Cross-Site Scripting (XSS) by lower-privileged users such as contributors, all via a similar method.
