The Pricing Tables for WP plugin for WordPress suffers from a reflected cross-site scripting vulnerability (CWE-79) via the 'page' parameter. This vulnerability exists due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of user-supplied data. An unauthenticated attacker can exploit this by crafting a malicious URL that, when clicked by an administrator, executes arbitrary JavaScript in the context of the administrator's session. This can lead to limited confidentiality and integrity impacts, such as theft of session tokens or manipulation of displayed content. The vulnerability affects all versions up to and including 1.1.0. The CVSS v3.1 base score is 6.1 (medium severity), with network attack vector, low attack complexity, no privileges required, user interaction required, and scope changed.

Successful exploitation allows an unauthenticated attacker to execute arbitrary scripts in the context of an administrator's browser session, potentially leading to disclosure of sensitive information or manipulation of the web interface. The impact is limited to confidentiality and integrity, with no direct availability impact. There are no known active exploits in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, administrators should avoid clicking on untrusted links that could exploit this vulnerability. Monitoring for updates from the plugin vendor is recommended to apply any forthcoming patches promptly.
