What the vulnerability does
The Nearby Now Reviews plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'data_tech' parameter of the nn-tech shortcode in all versions up to, and including, 5.2 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.
Explanation of Vulnerability in Simple Terms
Nearby Now Reviews versions 5.2 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts affecting other users across the site. An attacker with low-level account access can craft malicious input that executes in other users' browsers, potentially stealing session data or performing actions on their behalf. The vulnerability requires an authenticated account but no user interaction from the victim.
What an attacker can do
