How the CVE Works:
CVE-2025-1757 is a critical vulnerability in the WordPress Portfolio Builder – Portfolio Gallery plugin (versions up to 1.1.7). The issue arises due to insufficient input sanitization and output escaping in the ‘pfhub_portfolio’ and ‘pfhub_portfolio_portfolio’ shortcodes. Authenticated attackers with contributor-level access or higher can inject arbitrary web scripts via user-supplied attributes. These scripts are stored in the database and executed whenever a user accesses the compromised page, leading to potential data theft, session hijacking, or unauthorized actions.
