CVE-2026-4073

Beschreibung

The pdfl.io plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the -pdflio- shortcode in all versions up to, and including, 1.0.5. This is due to insufficient input sanitization and output escaping on the -text- shortcode attribute. The output_shortcode() function directly concatenates the user-supplied $text variable into HTML output without applying esc_html() or any other escaping function. 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.
