The vulnerability CVE-2025-62943 affects the 'Next Page, Not Next Post' WordPress plugin up to version 0.3.0. It is a stored cross-site scripting (XSS) issue caused by improper input neutralization during web page generation. An attacker with low privileges can inject malicious scripts that are stored and executed in the context of other users who view the affected pages. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with a scope change and limited impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to session hijacking, defacement, or other malicious actions affecting confidentiality, integrity, and availability to a limited extent. The medium severity score reflects these moderate risks. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting plugin usage to trusted users only and monitor for suspicious activity. Avoid exposing the plugin to untrusted users or consider disabling it temporarily if feasible.
