Cross-site scripting (XSS) vulnerability in the save_order function in class-floating-social-bar.php in the Floating Social Bar plugin before 1.1.6 for WordPress allows remote attackers to inject arbitrary web script or HTML via the items[] parameter in an fsb_save_order action to wp-admin/admin-ajax.php.

The Transients Manager plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.6. This is due to missing or incorrect nonce validation on the process_actions function. This makes it possible for unauthenticated attackers to delete transients via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The Sugar Calendar – Simple Event Management plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg & remove_query_arg without appropriate escaping on the URL in all versions up to, and including, 3.3.0. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The Smash Balloon Social Post Feed – Simple Social Feeds for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the data-color attribute in all versions up to, and including, 4.3.1 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 Charitable – Donation Plugin for WordPress – Fundraising with Recurring Donations & More plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the privacy settings fields in all versions up to, and including, 1.8.6.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled. This issue was partially fixed in version 1.8.6.1 and fully fixed in version 1.8.6.2.
