Stored XSS via unescaped shortcode parameters
Published Nov 11, 2025 · Updated Nov 11, 2025
Stored XSS in Sitedin WP Count Down Timer 1.0.1 and earlier allows remote authenticated users to inject scripts through shortcode parameters. The wp_countdown_timer shortcode renders multiple attacker-controlled parameter values without sufficient sanitization or output escaping, causing stored scripts to execute when an affected page is viewed. Contributor-level access or higher is required to store the payload, and execution is limited to visitors who open an injected page.
