This vulnerability in the WP-ShowHide WordPress plugin allows stored cross-site scripting due to improper input neutralization during page generation. Attackers can inject malicious scripts that persist in the plugin's output, potentially impacting confidentiality, integrity, and availability. The affected versions include all releases up to 1.05. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with a scope change and partial impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker with some privileges and requiring user interaction to execute arbitrary scripts in the context of affected users, potentially leading to data theft, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability to a limited extent. 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 limiting plugin usage or applying manual input sanitization if feasible. Monitor official Lester Chan or WP-ShowHide plugin channels for updates.
