The All-in-one Floating Contact Form WordPress plugin before 2.1.2 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 unfilteredhtml capability is disallowed (for example in multisite setup)

The My Sticky Elements WordPress plugin before 2.0.9 does not properly sanitise and escape a parameter before using it in a SQL statement when deleting messages, leading to a SQL injection exploitable by high privilege users such as admin

The Floating Notification Bar, Sticky Menu on Scroll, and Sticky Header for Any Theme – myStickymenu WordPress plugin before 2.5.2 does not sanitise or escape its Bar Text settings, allowing hight privilege users to use malicious JavaScript in it, leading to a Stored Cross-Site Scripting issue, which will be triggered in the plugin's setting, as well as all front-page of the blog (when the Welcome bar is active)

The myStickymenu WordPress plugin before 2.6.5 does not adequately authorize some ajax calls, allowing any logged-in user to perform the actions.
