The Latest Custom Post Type Updates plugin by David Wood suffers from a reflected cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows attackers to inject malicious scripts that execute in the context of the victim's browser. The vulnerability affects all versions up to 1.3.0. The CVSS v3.1 base score is 7.1, indicating high severity with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of a user's browser, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability of the affected system. The reflected XSS nature requires user interaction to trigger the malicious payload. No known active exploitation has been reported.
