Technical details

A Cross-Site Scripting (XSS) vulnerability exists in the Strategy11 Team Business Directory plugin for WordPress (versions <= 6.4.22) due to improper neutralization of input during web page generation (CWE-79). The flaw allows an authenticated attacker with 'Subscriber' level privileges to inject malicious JavaScript into the application. Successful exploitation requires a victim (such as an administrator) to interact with the affected page or perform a specific action, leading to the execution of the script in the context of the victim's session. The issue is resolved in version 6.4.23.
