What is CVE-2026-6672?

The SliceWP Affiliates plugin for WordPress is susceptible to Stored Cross-Site Scripting (XSS) through its shortcode attributes. This vulnerability arises from inadequate input sanitization and output escaping for user-supplied entries within the 'slicewp_affiliate_url' shortcode. As a result, authenticated attackers with contributor-level access can inject malicious web scripts into pages, which are then executed when users access the compromised page. This presents a significant risk, necessitating immediate attention to ensure robust security measures are implemented.

Affected Version(s)
