Researcher MTK (Muhammad Talha Khan)

Description

The Wise Chat plugin for WordPress is vulnerable to Reverse Tabnabbing in versions up to, and including, 2.6.3. This is due to mishandling of external links due to omitting noopener and noreferrer. This makes it possible for a chat-using attacker to provide a link that opens a new tab while silently redirecting the original - this can be used to redirect them to a phishing site on the original tab.
