The WP PT-Viewer plugin for WordPress, developed by Vincent Mimoun-Prat, contains a reflected cross-site scripting vulnerability due to improper input sanitization during web page generation. This flaw affects all versions up to 2.0.2 and allows attackers to inject malicious scripts that can execute in users' browsers when they visit crafted URLs. The vulnerability is remotely exploitable without privileges and requires user interaction. The CVSS 3.1 base score is 7.1, reflecting the potential for confidentiality, integrity, and availability impacts.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to theft of user credentials, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability of user data. However, no known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling or removing the WP PT-Viewer plugin or applying any available temporary mitigations recommended by the vendor.
