This vulnerability in the Shortcode Collection plugin by Agnel Waghela involves improper input sanitization during web page generation, leading to stored cross-site scripting (XSS). Attackers can inject malicious scripts that persist and execute when other users access the affected content. The issue affects all versions up to 1.4. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring low privileges and user interaction, with a scope change and impacts on confidentiality, integrity, and availability at a low level.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of users viewing the affected pages, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability. The medium CVSS 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 available, users should consider disabling or removing the affected plugin to prevent exploitation. Monitor vendor channels for updates and apply patches promptly once released.
