Summary
The Investi plugin for WordPress up to version 1.0.26 has a stored XSS vulnerability via the 'maximum-num-years' attribute of the 'investi-announcements-accordion' shortcode. The attribute is not properly sanitized, allowing authenticated attackers with contributor-level access to inject arbitrary scripts.
Risk Assessment
An attacker can inject malicious scripts that execute when a page is visited, potentially leading to session theft or other attacks.
Recommendation
Update the Investi plugin to the latest version.
Original NVD description (English source)
The Investi plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'investi-announcements-accordion' shortcode's 'maximum-num-years' attribute in all versions up to, and including, 1.0.26. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. Specifically, the 'maximum-num-years' attribute value is read directly from shortcode attributes and interpolated into a double-quoted HTML attribute without any escaping (no esc_attr(), htmlspecialchars(), or similar). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
