Bootstrap Multi-Language Responsive Portfolio WordPress Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Bootstrap Multi-language Responsive Portfolio plugin for WordPress, affecting all versions through 1.0. The issue arises from inadequate input sanitization and output escaping, allowing authenticated attackers with administrator-level permissions to inject arbitrary scripts. These scripts are executed when a user accesses the compromised page. This vulnerability is present in multi-site installations where unfiltered HTML is disabled.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the affected page.
